hehe yeahh its fun but i dont understand i got win in game but the result i lost some coins.. how to calculate it?
Payout calculation is described in the main post

Payout is determined as a ratio of player's hits to dealer's hits. However, dealer's shots are completely random, thus he is pretty disadvantaged. The Dealer cannot find player's ships after a hit. Because of that, final payout is 17:25.
