Gacha Tower DefenseTHE PLAYER'S GUIDE

MERGE-CANDIDATE CHECKER

Which tower levels can I compare for a merge?

Enter the counts of your starting-level towers. Find levels with a matching partner, then account for whether the current defense is holding.

Count your level 1–3 towers

Counts identify matching levels. This does not rank towers, simulate damage or predict the result of a roll.

YOUR PLAN

Find a match, then inspect the lane

A matching level satisfies the basic merge rule; the condition of your defense determines whether you should make a change now.
