Like Steeple Chase and Big Wheel, this giant allwin has a three-tiered layout, which diverts winning balls on the upper galleries to the lower galleries when the payout handle is turned, making multiple wins possible. Cannon Balls' has an exceptionally generous playfield, with four 3D win targets on the top gallery (compared with three 2D targets on the sister games) plus four bonus 'mystery win' cups which divert the ball for a free play or a 3D win. What's more, there's a setting to allow a free turn after a win on the bottom gallery. This must surely have been Wonders' least profitable allwin!
