Ember Field

Ember Field is a calm, one-thumb Lights Out puzzle. Every field is a small grid of glowing sparks, and your only goal is to switch every one of them off. The control is a single tap. Touch any cell and it flips between lit and dark — and so do its four orthogonal neighbours, in a plus shape. Because every tap changes five cells at once, the whole puzzle lives in the order you press them. Clear the edges and corners first and the centre falls into place. A live counter shows how many sparks are still lit; bring it down to zero and the whole field goes dark. Every field also carries a par — the fewest taps that can solve it — so there is always a cleaner line to chase once you have cracked the shape. Undo takes back a wrong tap and reset returns the field to its start, so no move is ever fatal. Ten fields climb from a gentle three-by-three opener to a dense six-by-six finish, each with more cells and more taps than the last. Nothing here is decided by luck or a wallet: there is no timer, no forced ad, and nothing to buy. Every field is built to be solvable with clear thinking alone, and your progress is saved on the device as you clear them, one grid at a time. Ember Field plays fully offline.
