Push Fish In The Pool:
🐟 - Tap on a fish to move it from the edge of the pool inward. Fish can only move directly to the space in front of them.
🐟 - Repeat the process until you can no longer move.
🐟 - The game playing field is a 4×4 grid, yielding 16 squares.
🐟 - All fish you push into the pool are numbered as 1, 2, 3 or 4. The right side of the playing field shows which number fish is next.

Create Merged Sets:
🐟 - Try to get 3 fish with the same number in a row across, horizontally, or in combination of the two directions to have the fish merge into a single fish of the next higher integer. The merge location will be wherever the most recent piece was placed to finish the 3 in a row.
🐟 - Merges can trigger a sequence of other mergers. For example, if you had three twos in a row and that merged into a 3 that could trigger a three threes merging into a four.
🐟 - If you get 3 number sixes in a row it merges into a number 7 which then disappears, removing itself and the fish from the 8 adjacent places from the game field.
