13MJVR’s CHAINING GUIDE
Because my chains broke although I entered the 4-zone patch, I decided to spend three weeks of my life to develop a new theory for chaining, because I read all guides posted in many forums, and any of them don’t seem to work for me. Well, after three weeks of proving patterns, I wrote a new chaining guide for obtaining shiny pokemon easier

This is the PATTERN THEORY made by me, 13mjvr
First, there are some aspects we have to remember when using this guide about other developed guides, the rest established by other guides MUST be forgotten, to succeeding when using my guide:
1. Max Repels (avoid non-pokeradar encounters), Poketch app 20 (show your number of chain), Swarms (easiest pokemon for chaining), Synchronizers (for obtaining good nature shinies), Static and Magnet pull (increase the chance of appearance of pokemon).
2. There are three types of patches: common, sparkly and Shiny. It’s very important to distinguish them while following this guide.
3. The number Chart:
4 4 4 4 4 4 4 4 4
4 3 3 3 3 3 3 3 4
4 3 2 2 2 2 2 3 4
4 3 2 1 1 1 2 3 4
4 3 2 1 0 1 2 3 4
4 3 2 1 1 1 2 3 4
4 3 2 2 2 2 2 3 4
4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Essential to see it while chaining with this guide: Type of patches and the number chart determine all the patterns.
4. Patches in the edge could break a chain (explained by Merbear), so all the following patterns AREN’T in an edge.
5. If you use a Max Repel after resetting, recharge and reset again.
6. 40th chain (or more) has the great chance of encountering a shiny patch.
That’s all of the other guides. Now, the following are some aspects that according to my research are incorrect from other guides, and indeed, must be ignored while using my theory:
1. “The 4-zone patch is the safest patch”
2. “Resetting affects the continuing of a chain”
3. “There are some unsafe tiles in the number chart”
Ok. Now, I’ll explain the main aspects of my theory required for understanding the patterns.
1. Essential to see the four shaking patches and the chart number while resetting.
2. There are PATTERNS which determine the zone with the highest chance of continuing a chain.
3. If any special PATTERN doesn’t appear during your chain, the chances of continuing a chain are the following:
a. 4-zone patch: High chance of not breaking your chain
b. 3-zone patch: Good chance of not breaking your chain
c. 2-zone patch: Medium chance of not breaking your chain
d. 1-zone patch: Low chance of not breaking your chain
4. A PATTERN is an arrange of patches that increases or transfers the chance of continuing a chain to a specific patch. A PATTERN could appear if:
a. The type of 1,2,3,4-zone patches are the same or different
4 4 4 4 4 4 4 4 4
4
3 3 3 3 3 3 3 4
4 3 2 2 2 2 2 3 4
4 3
2 1 1 1 2 3 4
4 3 2 1 0 1 2 3 4
4 3 2 1 1
1 2 3 4
4 3 2 2 2 2 2 3 4
4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Yellow: Sparkly-type
Red: Common-type
Starting with sparkly-type grass
In this case, the different patches suffer a decrease in its chance (3-4 zone) and the total decrease is added to the same-type patches (1-2 zone patches)
b. There are 2 or more patches in the same grass line
4 4 4 4 4 4 4 4 4
4 3 3 3 3 3 3 3 4
4 3 2 2 2 2 2 3 4
4 3 2 1 1 1 2 3 4
4 3 2 1 0 1 2 3 4
4 3 2
1 1 1 2 3 4
4 3 2 2 2
2 2 3 4
4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Underlined: Shaking patches
Patches in the same line could alter chances by switching their chances to each other, or by mixing their chances and obtaining new chances (equal chances or transfer chances to another zone)
c. There are 2 or more connected patches:
4 3 2 2 2 2 2
3 4
4 3 2 1 1 1 2 3 4
4 3 2 1 0 1 2 3 4
4 3 2 1 1
1 2 3 4
4 3 2 2 2 2 2 3 4
4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Red: Common-type
Connected zones transfer chances to the following zone.
d. There are 2 or more diagonally connected patches:
4 4 4
4 4 4 4 4 4
4 3 3 3
3 3 3 3 4
4 3 2 2 2 2 2 3 4
4 3 2 1 1 1 2 3 4
4 3 2 1 0
1 2 3 4
4 3 2 1 1 1
2 3 4
4 3 2 2 2 2 2 3 4
4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Yellow: Sparkly-type patches
Diagonal patches cause an alteration in all the four patches’ chances. This modification has some chance of breaking chains.
5. PATTERNS maximize the chance of not breaking your chain. However, some of them aren’t 100% safe.
6. Chance of appearance affects the chains. So:
a. 24% or less chance of appearance pokemon: Chained pokemon in 0-1 tiles.
b. 25-49% chance of appearance pokemon: Chained pokemon in 1-2 tiles.
c. 50-74% chance of appearance pokemon: Chained pokemon in 1-3 tiles.
So that means as high the chance of appearance, as high the chance of more tiles containing the chained pokemon. That’s the reason why I proved this theory with 24% or less chances pokemon: When you chain a higher chance pokemon, you have more probabilities of continuing your chain if you make a mistake with the following patterns.
PATTERNS
All these patterns were proved when starting with Sparkly type grasses. So I recommend using them too. Proving this theory with common-type patches requires another two weeks…. However most of the patterns should work similarly. But I read time ago, a theory of type of grasses: it said that was impossible to switch a sparkly-type to a common-type patch while chaining, but sometimes you can switch a common-type grass to a sparkly-type grass and your chain doesn’t break, so this give more support to the idea that the sparkly-type are the best for using the following patterns.
LINE-PATTERN: one main pattern of my theory. When you start with common or sparkly type grasses, and if ANY two patches are on the same line, the chance of breaking your chain if you enter the 4-zone patch increases.
For example:
3-4 zone patches in a line
4 4 4 4 4 4 4
4 4
4 3 3 3 3 3 3 3 4
4 3 2 2 2 2 2 3 4

4 3 3 3 3 3 3 3 4
4 4 4 4 4
4 4 4 4
I entered hundred of times to this kind of arranges and I have a lot of chain breaks. I also entered patterns which didn’t have patches in-a-line, and almost all my chains continued. No-lined patterns according to my data have 85-90% of working, so they’re very safe. According to what I have seen, two-lined patches alter the normal chances of patches by mixing chances one with another, for example, if the 3-zone and the 4-zone patches are in a line, both patches “mix” and may have the highest chances of continuing a chain, so 4-zone aren’t completely safe (I proved this a lot of times and I got a 41% for 3-zone patch and 59% for 4-zone patch, assuming that the chain pokemon was on those patches) I also proved this with other two-lined patches and had similar results. So, when you see lined patches, is recommended to Reset your pokeradar and search no-lined patches. But that doesn’t mean that if you enter a lined pattern, your chain will break instantly, some of them can continue, but they have a lower chance that no-lined patterns. Some safe arranges according to this pattern would be:
4 4 4 4 4 4 4 4 4
4 3 3 3
3 3 3 3 4
4 3 2 2 2 2 2 3 4
4 3 2 1 1 1 2 3 4

4 3 2 2 2 2 2 3 4
4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
And others. Important to apply this pattern when others patterns appear.
Note:
Yellow: Sparkly-type patches
- 4-ZONE GLOWING PATTTERN (Free +1 to your chain): When starting with Sparkly-type patches, if the 1,2,3 zone patches are of common type, and the 4-zone patch is of sparkly type, the 4-zone patch has a 99-100% chance of continuing your chain. This pattern is prior to any other pattern. For example:
4 4 4 4 4 4
4 4 4
4 3 3 3 3 3 3 3 4
4 3 2 2 2 2 2 3 4
4 3
2 1 1 1 2 3 4
4 3 2 1 0
1 2 3 4
4 3 2 1 1 1 2 3 4
4 3 2 2 2 2 2 3 4
4
3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Red: Normal-type Grass
Yellow: Sparkly-type Grass
This is the safest patch possible. This happen, because 1,2,3-zone patches are of normal-type so its chances of continuing the chain decrease, and the decrease total chance is added to the 4-zone patch (because it’s of the same starting grass type). This seems to work similar when you start with common-type patches, but instead, 1,2,3-zone patches must be of sparkly-type and 4 patch of common type.
With this pattern, some chainers could think that something similar will occur when 1,2,4-zone patches are of common-type and 3-zone patch of sparkly type for example (if starting with sparkly type). I proved this kind of patterns a lot of times and they could work, but the greatest results appeared with the 4 glowing patch. As I explained before, 1-2 and 3-zone patches has less chance than the 4-zone patch in “normal conditions”, so maybe the additional chance couldn’t be enough for 1,2 zone patches to be higher than the normal-type 4-zone patch’s chance, and this causes a chain to broke. Entering this pattern when the 3-zone patch is the glowing patch has about 60-75% chance of working.
NEVER-SAFE PATTERNS: When you start with sparkly-type patches, if ALL four patches are of normal-type, your chain has a 100% chance of being broken if you enter any patch. This pattern seems to appear with 22% or less chance of appearance pokemons, and this could happen because any of the four patches contains the chain pokemon. In that case, reset again.
When you start with Sparkly-type patches, and normal conditions appear (no lined patches, separated patches, no diagonal patches), if the 1,2,3 zone are of sparkly-type, and the 4-zone patch is of common type, the higher chance of the 4 patch is decreased and is added at random to another patch. So, is impossible to determine which patch contains the chain pokemon (if anyone has it). In that case reset again.
DIAGONAL PATTERN: When starting with Sparkly-type grass (also seems to work with normal-type), if any of the patches is connected diagonally with another patch, the normal chances of 1,2,3,4-zones are altered and a chain could be broken. FE:
4 4 4 4 4 4 4 4
4
4 3 3 3 3 3 3
3 4
4 3
2 2 2 2 2 3 4
4 3 2 1 1 1 2 3 4
4 3 2 1 0
1 2 3 4
4 3 2 1 1 1 2 3 4
4 3 2 2 2 2 2 3 4
4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Yellow: Sparkly-type
In this case, the 4-zone patch would normally have the highest chance, however, being connected with the 3-zone patch causes some alteration on the zone patches, and could make the 3-zone the safest place for the chain (It seems both have similar chances). The diagonal connection between 1-2, 2-3 zones could also alter a chain (they’re other patterns, but I couldn’t determine how the chances are affected, but I got a lot of broken chains with those patterns when entering the 4-zone patch). So, when a diagonal appears, the safest option is resetting again.
- TWIN PATTERN: When two patches are connected (normal-type), their chances of containing the chain pokemon decrease and they’re added to the following zone patch. This pattern was proved with Sparkly-type, seems to work with common-type, but it hasn’t be confirmed.
a. 1-2 NORMAL TWIN PATTERN: When starting with Sparkly-type patches, if the 1 and 2-zone patches are connected and of normal type, and the 3-zone patch is of sparkly-type, the 3-zone patch has a very high chance of continuing a chain. For example:
4 4 4
4 4 4 4 4 4
4 3 3 3 3 3 3 3 4
4 3 2 2 2 2 2
3 4
4 3 2 1 1 1 2 3 4
4 3 2 1 0
1 2 3 4
4 3 2 1 1 1 2 3 4
4 3 2 2 2 2 2 3 4
4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Red: Normal-type
Yellow: Sparkly-type
b. 2-3 NORMAL TWIN PATTERN: When starting with Sparkly-type patches, if the 2 and 3-zone patches are connected and of normal type, and the 4-zone patch is of sparkly-type, the 4-zone patch is the safest place for continuing a chain (80-85% of chance).

4 3 3 3 3 3 3 3 4
4 4 4 4 4 4 4 4 4
Red: Normal-type
Yellow: Sparkly-type
c. 3-4 TWIN PATTERN: When starting with Sparkly-type patches, if the 3-4-zone patches are connected and of sparkly type, the 4-zone patch has the highest chance of continuing a chain (no following zone to transfer the chance, so I think it remains in the 4-zone patch). This chance could be increased to 80-90% if the 1-zone patch is of normal type, and to 95-100% if the 1-2 zone patches are of normal type.

Yellow: Sparkly-type
- 2,3,4 CONNECTED PATCHES: When starting with sparkly-type grass, if all the four patches are of sparkly-type and 2,3,4-zone patches are connected, the 1-zone patch has the highest chance of continuing a chain (I couldn’t prove this a lot of times, because this kind of arrange is very rare, but I have enter about 12 times to this pattern and it worked).
4 4 4 4 4 4 4 4 4

Yellow: Sprakly-type
Connected patches transfer its chance to the following zone, so because the 1-zone patch is the only not connected, it obtains the additional chance.
- FOOT PATTERN: When starting with Sparkly-type grasses, if 1-2-zone patches are connected (twin) and 3-zone patch is diagonally connected to the 2-zone patch, a foot pattern appears. If the 1,2,3-zone patches are from sparkly type, the 3-zone patch has the highest chance of not breaking your chain (75-80%). If the 4-zone patch is of normal-type grass, the 3-zone chance increases.

4 4 4 4 4 4 4 4 4
Red: Normal-type
Yellow: Sparkly-type
- 3-IN-LINE PATTERN: When starting with Sparkly-type grass, if three patches are on the same line (one of the patches is the 4-zone one), is not possible to determine which patch contains the highest chance of continuing a chain.
4 4 4 4 4 4 4 4 4

4 4 4 4 4 4 4 4 4
Yellow: Sparkly-type
That’s because normally the 4-zone patch has the highest chance, but being in line with another 2 patches causes a mix between their chances (eventually the 4-zone highest chance could be transferred to another patch in a line, so that causes a chain break)….so any of them could be the best patch. If a 3-in a line pattern appears and the 4-zone patch is not in the line, the 4-zone patch maintains the best chance of continuing a chain. However, there’s some risk in entering this zone…. The best option when a 3-in-a-line pattern appears is to RESET again.
- 1,2,3 LADDER PATTERN: When starting with Sparkly-type grass, if the 2,3,4-zone are connected diagonally and of sparkly-type, the patch in the medium of the ladder has the highest chance of continuing your chain (75-85%) in “normal conditions” (1-zone patch not in line with any patch of the ladder).

Red: Normal-type
Yellow: Sparkly-type
When the 1-zone patch is in line with any of the ladder patches, the high chance seems to be transferred to the patch of the ladder in a line with the 1-zone patch. However, this makes it an unsafe patch, so when it appears, is recommended to reset again if you are in a high chain.
------------------------------------------------------------------------------------------
There’re other patterns as well that I have noticed, but they need to be proven more times, but the above patterns are the main ones from my research. I’ll add others as soon as I have more time to begin another research, but I think this guide will help you to get easier a 40th chain of any pokemon

Thanks Pokerealm for helping me proving some patterns. I hope this guide will help all chainers with their chaining skills.
