Gachapon machines in Japan dispense a random capsule toy for a coin. This simulator wraps the idea around a three-reel slot: the Shibuya Gachapon machine pays with 100-yen coins, taiyaki and mecha cat paws, and its gacha tube opens a capsule every 50 spins.
Spin and watch the tube fill. Two golden tickets start a bonus round. The math section shows how much the capsule adds per spin and how often a 50-spin session hits a bonus.

The gacha tube fills by one segment per spin and opens a 2,500-coin capsule every 50 spins. At a 50-coin bet that adds 50 coins per spin on top of the machine's RTP: a fixed reward that does not depend on luck. In 2,000 simulated 50-spin sessions on Degen, 36% of sessions triggered at least one scatter bonus.
Exact figures for Shibuya Gachapon, computed from the reel weights and paytable. Chill and Degen use the same 94.0% return to player; only the distribution of wins changes.
| Mode | RTP | Hit rate | Std dev per spin | Top line pays | Bonus chance |
|---|---|---|---|---|---|
| Chill | 94.0% | 19.2% | ×7.2 | ×501 | 0.9% |
| Degen | 94.0% | 16.6% | ×11.7 | ×372 | 0.9% |
Exactly every 50 spins, whatever the results. It is a fixed reward, so it adds a steady amount per spin rather than a lucky jackpot.
No purchases are possible. Coins are virtual, have no cash value and cannot be bought, so nothing of value is won or lost.
