Summary: A standard match-3 game. You have to match over all the tiles in the levels. The later levels can get really annoying, just trying to match over one little tile for a long while and running out of time. Otherwise, it's fun, and a nice bonus is being able to unlock fish the more you play and using your fish as a screensaver.
Summary: Big Kahuna Reef is great! It has a timeless mode which I use so I can watch the very realistic fish swim in the reef. Any game which doesn't make me play against the clock is good, but this one is truly relaxing to play.
Summary: This game is a great little time-waster. I sat down for a quick game and ended up playing for hours. While challenging, this isn't a game that's going to frustrate you. Too many stress-relief-type games leave me more stressed out than I was to begin with, but Big Kahuna Reef is genuinely pretty fun to play. You basically just have to match puzzle pieces together until all of the tiles have been "used," so even a child can play pretty much right of out of the gate.
