It's colorful. It's free. It's relaxing. It's Hexic HD.
You go around the board, shifting the hexagons around to combine 3 of the same colors together, making them vanish and more hexagons taking their place. Sometimes, bomb pieces will come out and you have to get rid of them in a certain amount of turns. In survival mode, you have to clear as many of these hexagons off of the board, until you can't anymore, and those left behind are locked onto the board.
The game is full of simple, pretty colors, so it wont cause any eye strain. The sound effects are quiet and pleasing to the ear. There isn't any music in the game, but that helps with the relaxation part (although you could play whatever you want off of your harddrive).
So if you're tired of Halo, Cod, whatever you kids are playing these days, kick back, relax and play a game of Hexic HD
...also, I have no idea if you can get this game back if you delete it from your harddrive, so don't!
