Fourder

Enter the numbers to the gameboard in the correct order to solve each challenge.

Test your puzzling skills with Fourder! No Mathematics Ph.D needed, only the ability to think ahead and some logical reasoning.

The goal of the game is simple. Start off with a blank gameboard that contains empty cells and walls. In each phase you get one number (which can be found inside the black circle in the center of the scceen). You need to feed this number to your gameboard from a particular direction (by choosing one of the four arrows on its sides). A number-feed will add up your phasenumber to what's already on the board, but will stop when it encounters a wall. To win, simply have your gameboard containing the exact same setup as the board in the bottom of the screen when the last phase ends.
