Despite what you might be thinking, Pi-Pi-Ee is not the sound children make when they want some desert on Thanksgiving (though I'm sure it's very similar). It is the mathematical title of the Othello-like strategy puzzle game from Chris Underwood who also brought us the Hanna in a Choppa games. You start out with several pieces on a game board with the goal to outnumber your opponent. Click and drag to move your creatures around. You can move a piece one square (or hexagon, or triangle) away, and it will clone itself. Alternately you can jump your piece two connected spaces away from its current location, leaving the space you jumped from empty. If your creature lands next to an opponent piece, you capture it, and it changes to your color. Click and hold on one of your guys to highlight possible valid moves. The game is over when all the spaces are full, or if one player can't make any more moves.
The first few levels are simple enough, but it gets challenging soon enough, and if the AI isn't tough enough for you, grab a friend for two player mode and show 'em what you got. The board set-ups vary wildly, which keeps things from getting repetitive. A game on a board with squares can be vastly different from a board of triangles, and many levels combine shapes for even more interesting set ups and strategies. Sometimes being aggressive is the way to go, while other times blocking your opponent in the corner might be beneficial. Paying close attention to which spaces are connected to which, indicated by glowing blue lines, can be the difference between a win or a loss. If the web version leaves you wanting more, pick up the game for your mobile device which features more levels and an unlockable harder AI opponent. As a bonus, there are no in-app purchases whatsoever. Simple to learn, hard to put down, Pi-Pi-Ee is a wonderfully strategic game that will keep you coming back for more.
