This is the most INFURIATING flash game I have come across. You have to fit tiles together to make a path to get a monkey across a river. Problem is the tiles are random, and half of them don't combine, and you only get nine to play with.
I admit defeat.
If anyone can get that fucking monkey across the river, I will personally tip my hat to you, sir.
