Coin Field is a mines-style arcade game from 1X2gaming, rather than a reel slot. Players choose the board size and number of hidden mines, with those settings changing the multiplier schedule. The task is to reveal safe positions while avoiding a mine; the selected configuration therefore needs checking before a round starts. Its official gamecard lists several RTP versions, so the exact installed version matters. Coin Vault offers a bank-vault presentation of a related format, while Coin Field is the separately named release.
The library also explains how crash and instant-game rounds differ to help put these mechanics in context.
