Big Kahuna Reef is a tile-matching puzzle video game developed by Reflexive Entertainment.

The look of the game is that of ocean scenes, exotic fish and tiki heads.

To pass the level and progress, a player must break all of them by making chains of objects (such as starfish or shells), before the time runs out.

[4] Between levels, points are earned that unlock new fish and other undersea creatures.

[5] During the interludes between levels, one can create and observe their personal reef and its creatures in the Fish Screen mode.
