The exciting puzzle Chain Reaction Grid invites you to start a chain reaction on a compact field. Each tile has a counter and a shot vector. Activate any block to send a pulse to neighboring elements. When hit, the cell's charge decreases, after which it shoots itself. When the value drops to zero, the block disappears, clearing the way for other projectiles. Empty spaces allow charge to pass through, so routes are constantly changing. Calculate the consequences and earn game points for victories.
