A fair disclaimer: I’m also competing in the Cup. I’ll try to be unbiased though, judge for yourself and give the games a try!
This is an HTML5 “Tower Defense” game but with a rather unique twist: You have to solve math problems to activate your towers.
There are archers with simple math problems positioned strategically to hit the spawning skeletons. Answer the problem correctly and the archer shoots. There is
no a penalty for guessing though,which is an exploit that I saw my brother quickly abuse by slamming numbers until he got one right in the higher levels.
I really enjoyed this simple game. The presentation is fantastic, the idea is clever and the execution is well done.
Update: There is a penalty for guessing: Your score is lowered every time you guess wrong. My brother’s exploit only serves to explore the higher levels but your score will always near zero.
