Drag two identical fish together to merge them into a higher-level fish.
Most things are pretty intuitive once you start playing. If something feels off, the first level usually doubles as a tutorial.
Tips for New Players
- Merge your lowest-level fish first to free up space on the board.
- Do not hoard rare fish hoping for a specific merge. The board fills up fast.
- New fish types appear as you reach higher levels. Keep merging and they will show up.
- If the board is nearly full, merge anything you can — even if it is not the ideal combo.
