In the Metin2 fishing event you place pieces from fishing puzzle boxes on a 6×4 board. The reward depends on the number of moves: up to 10 moves gives the Large Gold Fish Chest, 11–24 moves the medium one and 25 or more the small one. A luxury box always gives a big 2×3 piece.
For each piece, the helper checks every spot on the board and picks the one with the best chance of filling the board within the move limit. It also tells you when to throw a piece away and when to use a luxury box.
The board has to be filled in 10 moves or fewer. Every box you open counts as a move, even if the piece does not fit.
A luxury box always gives a 2×3 piece, so it helps most when there is room for it and your chance of the large chest is at risk. The helper compares your odds with a luxury box and with a normal one.
No. The game cannot be abandoned: you have to fill the whole board, so when the chance of the large chest gets low the helper switches to safely aiming for the medium one.
