The Gapwin is an allwin with a very effective twist - one ball for a penny, you aim for the wide gap between the two lose cups. If successful, the weight of the ball tips over the first gate obstructing the gap and rolls back to the firing hammer. The player must now repeat the performance to remove the second gate, exposing the three win targets beneath. A third successful shot releases the payout handle. The game can be set to offer players a fair chance; the operator can adjust the gap (by moving the left lose cup) and can set payouts to coin return only, up to a maximum of 2, 6, 4 on the three targets. The ball can also be returned to play following a win. A variable pressure unit tries to throw the player off by altering spring tension between wins.
If a player loses after opening one or two gates, there's a strong incentive to insert more money to jump the last hurdle. By the same token, if a player gives up having cleared the gates, another player will be tempted to complete the job.
