Lock n' Chase — About this game
Lock n' Chase follows a bank robber through mazes whose coins must all be collected before the next stage. The police are slower, but a poorly chosen turn can still leave you cornered. Put a barrier behind you to cut a pursuit or isolate an officer, remembering that only two can stand at once. Money bags briefly freeze the chase and spinning diamonds give a safer moment to cross danger. Pause to inspect the rest of a large maze, then choose a route that joins the remaining coins instead of simply running toward the nearest one.
Press START and plan a loop through the first coins. Move with the pad and use A or B to leave a barrier behind you when police close in. If the maze extends offscreen, pause with START and scroll with the pad before choosing the next turn.
