Return to the Hawaiian waters to do some more matching.
Big Kahuna Reef 2: Chain Reaction is Big Kahuna Reef only bigger. You still use your mouse to swap tiles to create a row of three or more but now you have seven-hundred fifty possible levels to play through. To clear the levels, you must make matches on or explode wooden planks. When all the wooden planks are clear, the level is clear. If there are metal planks, you must match or explode them twice. If you match five of the same, you create a bomb, which destroys a large area on tiles. During the game, dynamite is also created that destroys a smaller area.
