Mentat.pngMath can make for great puzzles, as it does in Frank Mitchell's Mentat. Based on the card game DOM, players earn points in Mentat based on where they place numerical chips on a 4x4 grid. There are 52 chips, numbered 1-13, must like a deck of cards. Players earn points when placing a chip in the rows, columns, and major diagonals and meeting certain conditions.

Players earn one point for making a multiple of 3, 5, or 7 in any of those areas. Placing the first chip divisible by at least one of those three numbers in one of the corners would net 3 points off the bat, as that would create a common multiple in one column, row, AND major diagonal. They also earn points from making two, three, or four of a kind, or four consecutive numbers in those areas.

The developer recommends Chrome, Safari, and Opera to play Mentat. To play against a friend, simply click the yellow monitor above the game board. The AI is rather tough! I barely won the game above, after losing a few. Good luck with this great js13kGames entry!
