Metin2 Jigsaw Puzzle Guide: How to Solve the Fish Chest Jigsaw
The jigsaw from the fish chest is the part of Metin2 fishing most people think is pure luck. It is not: two players drawing the same pieces can differ by 16 versus 33 draws per chest. This guide covers the rules, the reward thresholds and the best strategy, measured over 5,000 simulated games.
Rules and reward thresholds
- The board is 6×4 = 24 cells. Every click on the chest gives you one of 6 piece types at random.
- Pieces do not rotate; you must fit them exactly as they arrive.
- You do not have to place a piece — you can discard it, but the draw still counts.
- The reward depends on how many draws you need: 10 or fewer = Large chest, 11–24 = Medium, 25+ = Small.
The 6 pieces and which ones are dangerous
The pieces: Corner (3 cells), L (3), Square (4), Vertical bar (3), Z (4) and Single (1). Each arrives with equal probability (1/6). The problem is not the big pieces but the single-cell holes they leave behind: only the Single piece can fill one, and waiting for it costs about 6 draws on average.
Best strategy: sometimes discarding is right
Intuition says “I paid for this piece, so place it.” Solving every board state shows otherwise: if a placement opens an isolated hole, discarding and losing one draw is cheaper. “Always place” costs 20.8 draws per chest on average; the optimal strategy that discards when needed gets 16.4.
- Start from corners and edges; do not leave islands in the middle.
- Before each placement ask: does this leave a single cell nothing can fill? If so, discard.
- Save Square and Z for 2-row empty strips; the vertical bar for 3-cell column gaps.
- In the last cells wait for the Single piece; do not ruin the board with random patches.
Benchmark: four strategies over 5,000 games
| Strategy | Avg. draws | Large | Medium | Small |
|---|---|---|---|---|
| First fit | 32.8 | 1.3% | 30.3% | 68.4% |
| Heuristic | 25.3 | 4.7% | 51.8% | 43.5% |
| 2-move lookahead | 23.5 | 6.3% | 55.3% | 38.4% |
| Exact table (DeepCast) | 16.4 | 12.7% | 77.8% | 9.6% |
The gap is huge: a naive player closes two thirds of chests as Small, while optimal play drops that below 10% and ends 90% of games with a Medium or Large chest.
