Math Mountain

Adjust difficulty and answer math questions. Play against computer or another human.
Your goal in this game is to climb to the top of the mountain by answering simple math questions faster then you opponent. You are allocated different IQ points for answering a question correctly. You are also awarded bonus IQ points for answering a question in less than 10 seconds.

Each turn a correct answer allows you to move up the mountain 1, 2 or 3 steps based on how hard the question was or back the same number of steps if you answer incorrectly.
