Far too often, I find myself in situations where I make a crit tile, and it falls in line with multiple match lines. What gets priority? By priority, I mean which line gets the benefit of the crit. I know that one will get the benefit of the critical, the second line will still disappear and generate AP, getting credit for the wild card nature of the crit tile, but the effect won’t be a critical.
I thought of a variety of guesses, but I can’t seem to confirm any one over the other.
-do color matches get priority over environmental title matches? (partly true)
-do 5s get priority over 4s, which get priority over 3s? (false)
-do horizontals get priority over verticals? (false)
Edit:
First off, credit to Beezer37_84 for teaching me that team orientation plays a part in battle. (https://forums.505go.com/discussion/4853)
In a nutshell, if you come into combat with characters with equal match strengths, the game uses the order on the team selection screen to decide who takes which color. The order is center, left, right. On the boost screen, it’s left to right (left, center, right)

In this setup, the colors would be controlled as follows:
Yellow: 52 Magneto
Red: 60 Hulk (Beats Magneto’s 60 due to team orientation)
Blue: 67 Magneto
Purple: 67 GSWidow
Green: 67 Hulk
Black: 52 Hulk (Beats GSWidow’s 52 due to team orientation)
ET: 4 GSWidow
So, crit ties. I’ll start by focusing on ET (environmental tiles) because that’s what caused this whole research for me, wanting to make ET crits. Which line gets the crit is based on the same team orientation priority. In this setup I have here, GSWidow is in charge of my ETs. Since she’s behind Hulk, any ET crit ties with any of Hulk’s colors will go to the colors.
ET and Red = Red gets crit bonus
ET and Green = Green gets crit bonus
ET and Black = Black gets crit bonus
Widow is in charge of Purple. In the case of a tie between ETs and a color your ET character controls, the color also wins.
ET and Purple = Purple gets crit bonus
Now, since Magneto is in spot3, his match colors lose priority to the ETs in a crit tie.
ET and Blue = ETs get the crit bonus
ET and Yellow = ETs get the crit bonus
Strength of the color makes no difference.
Crit bonus multiplier makes no difference.
Specific characters make no difference.
All that matters is what order your team is set in, and who controls which color.
Lets say for example, I were to reorganize my team to:
Left: Magneto
Center: GSWidow
Right: Hulk
We’d get the following results:
Yellow: 52 Magneto
Red: 60 Magneto (Beats Hulk’s 60 due to team orientation)
Blue: 67 Magneto
Purple: 67 GSWidow
Green: 67 Hulk
Black: 52 GSWidow (Beats Hulk’s 52 due to team orientation)
ET: 4 GSWidow
ET crit ties would look as follows:
ET and Yellow = ETs get crit bonus (GSWidow has priority over Magneto)
ET and Red = ETs get crit bonus (GSWidow has priority over Magneto)
ET and Blue = ETs get crit bonus (GSWidow has priority over Magneto)
ET and Purple = Purple gets crit bonus (internal GSWidow, color takes priority)
ET and Green = ETs get crit bonus (GSWidow has priority over Hulk)
ET and Black = ETs get crit bonus (internal GSWidow, color takes priority)
On a strategic note, if you want your crit ties to go to your ETs, put your ET match character center. If you want all the ties to go to your colors, put them in the right spot. If your ET match character is in the right spot, your ET crit ties will never go to your ETs. This is because every color will either be controlled by spot 1 or 2, thereby takig priority from the ETs, or spot 3, making it an internal conmpare, giving priority to the color.
As far as one color versus another in a crit tie, the same logic applies. Strengths don’t matter, higher numbers of tiles don’t matter.
Example:

In this screenshot, I lay a crit tile on the highlighted spot.
Green is controlled by Wolvie2star, lvl 29, center spot, 19 str, 4.0 crit
Black is controlled by GSWidow, lvl 141, left spot, 52 str, 4.0 crit
The greens took the crit, even though GSWidow had more damage, and more tiles matching. Wolvie2star had the team orientation priority.
So, keep this in mind when matching crits, it could mean the difference between and 150 crit and a 1,150 crit.
