Merge Master: Idle Zombie War

We have reached a dead end and there’s no way to move forward with the game. We have accidentally filled all the squares with different characters and cannot acquire further zombies or shooters to merge (and not even given an option since there’s no free space ) There also doesn’t appear to be a way to get rid of /delete characters to create space so now we are stuck! On top of watching a TON of ads….

My little cousin and I like to play this game, until recently the scary girl “Momo” has been popping up on these ads and scaring my little cousin. Please remove these immediately to avoid further kids getting scared.

Avoid unless you love ads from these developers who don't understand we aren't trying to put their kids through college.
