Jelmata: Strategy Board Game
Expand. Multiply. Conquer.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Jelmata is a strategy game in which your score is the product of the sizes of your connected components. Place cells on the board, and any that touch orthogonally form a group. One group of 6 scores just 6. But split that into groups of 4 and 2? That's 4 × 2 = 8. This one rule changes everything. Do you extend a group to block your opponent, or break away to start a new one? Every cell you place shifts the math for both players — and a single move can flip who's winning.
