This game came out 12 years ago for the playstation and to this day, it's still one of my favorite attack puzzle games of all time. It's a perfect adaptation of the original playstation version too and has lots of secrets to uncover. For those who have never played it before, the idea is to match up gems of similar colors to build up their size, and when a flashing "gem breaker" comes down that matches the color of the gem, it will break the built gems and send over stacked gems for your opponent to deal with and of course they can do the same to you. The game is EXTREMELY addicting.
