Tropical Fish Shop: Annabel's Adventure

At the end of a diving vacation, Annabel decides to chase her dreams by quitting her office job back home, and hiring on as a diver-for-hire catching fish for a local tropical fish shop. The business is in financial difficulties, and can only survive if Annabel succeeds in catching all the animals on the shop owner's daily task lists.

Catching fish is performed in a match-3 game, where three or more items on a grid have to be aligned into a horizontal or vertical line by swapping adjacent pieces. All the fish that need to be caught are part of the grid, and any that are removed from the field by winning moves get checked off the list. The goal of each round is to complete the list before Annabel's air runs out. Removing the special air bubble tiles from the field replenishes air, and as players progress through the rounds, they earn better diving equipment with higher air capacities. Catch nets allow to remove selected pieces from the field, and are upgraded as well, allowing to remove more items at higher levels. They need to be charged before use by achieving several matches of four or more items.

Special rounds include concentration-style games where the player has to find matching pairs among covered tiles, and diving competitions, where a computer-controlled opponent takes turns trying to catch the fish before the player manages to do so.
