You are in :Skill Monkey Games
The intro story doesn't make much sense and has little to do with the game itself. It speaks of the coming of a man who had decided to build the factory in the midst of the jungle, somewhere in the woods of 'Monkenya'. Using dynamite, axes and heavy machinery he had cleared one piece of the forest and thus destroyed a piece of the monkeys habitat. You should somehow, by playing this game, help the monkeys to win back and afforest that piece of land again, but it is not all that clear on how is all that supposed to happen and what are you actually doing to help...
How to play
This is a logic game. So, we have one static screen where you play against the computer. You have your pile of numbered stone blocks, computer has its own and there is a mutual little pile in the middle. Taking turns, you and computer take one block at the time from the middle pile and change them for one of your blocks. You can always choose either 2 offered numbers or 1 number and a question mark in which case the number is especially drawn instead of the question mark. The goal is to arrange the numbers in descending order from bottom to the top. You get special points for arranging consecutive numbers next to each other. The one that menages to do it first is the winner and then you move to the next level.
