merge fish in a dark cave.
Fish Cave Merge is a relaxing drag-to-merge board game where you slate. Spawn pet eggs onto a 5×7 grid, then drag any two identical pets on top of each other to merge them into the next stage of evolution — Fry into…
1. Tap SPAWN EGG (or Space) to drop a Roe onto an empty grid cell.
2. Drag any pet on top of an identical one to merge them into the next evolution.
3. Each merge earns coins (value doubles per tier) — spend them to spawn more eggs.
✦ Free drag-to-merge board — move every pet by hand, not a fixed slide
✦ An 8-stage evolution chain from Roe to Kraken
✦ Coin economy: merges pay out (doubling per tier) to fund more eggs
