Duelbarrow

Duelbarrow is a top-down tank duel among old barrows where the field is built by the fight. A shell that hits nothing settles where its flight ends, or where it strikes stone a second time, and raises a cairn in its tank's colour. Your own shells fly straight through your cairns and leave them faster, so they are cover with firing slits; the rival's shells stop on them and crack them, and a second hit breaks one. Both tanks are blocked by every cairn, five of yours can stand at once and a sixth sinks the oldest. Each tank has two plates of armour, so two hits win a round, and your own ricochet can hit you; if a round runs long, the cairns sink one by one. Climb a ladder of six rivals in three barrows, each with its own way with the stones, play a friend on one keyboard or with two gamepads, or take the daily barrow that is the same for everyone. Relics give a keystone cairn, shatter shots or a long throw. It plays in the browser with a keyboard, mouse, touch or gamepad.
