Play Prison Thimbles For Real Money

Unfortunately, no matching casinos are available in your country. But don’t worry, we’ve found some other ones you might like!

How to play

As mentioned above, this is not a traditional slot game. We would describe it as an instant-win casino table game. Jack is the “dealer” and he has three thimbles in front of him. He will mix the thimbles, and you have to guess which one the ball is under. It's like the traditional cup and ball games you see at carnivals!

On the right-hand side, you can change the bet value using the plus and minus icons. The minimum bet is €0.50 and the maximum bet is €10. As a result, high rollers may not be a fan of this game. You are essentially betting on if you choose the correct thimble or not.

There is also a max bet option so you can instantly choose the maximum bet value of €10. We also like that in the top-left corner, there is a diagram showing your recent bet history together with where the balls were located under the thimbles.

Symbols and payouts

The Prison Thimbles slot does not have any symbols. It simply has cups and you must choose the correct one. There are two game modes - 2 balls or 1 ball. In the 2 balls game mode, jack places a ball under two separate cups - therefore, only one cup is empty. This game mode gives you a much greater chance of winning (it should theoretically be 66.66% or a 2 in 3 chance of picking correctly). However, due to the increased win rate, it gives a lower payout of 1.44x your bet value.

Alternatively, there is the 1 ball game mode. In this mode, Jack places one ball under one cup. As a result, you have a lower chance of picking the correct cup - effectively a 33.33% chance or a 1 in 3 chance. Due to the lower win chance, the payout multiplier is higher at 2.88x your bet value.

To play, first, select the game mode - either 2 balls or 1 ball. The options for these are on the left-hand side and you can switch game mode at any time after or before a shuffle. With a game mode selected, you then press the shuffle button - Jack will place a ball (or balls) under the cups and shuffle them. You are then given three options to pick from - left, center, or right - pretty simple!

Best Prison Thimbles bonus feature

There is no Prison Thimbles bonus feature or Prison Thimbles free spins. There is, however, an interesting double or nothing feature. In the single-ball game, if you lose your initial choice, you can choose the double or nothing option.

Here you can essentially bet again on the remaining two cups for an extra stake. This narrows your chances of winning down to a 50/50 choice.

RTP & volatility

This unique game from Round Circle is not like any traditional video slot. However, it still has a theoretical RTP rating. Therefore, the Prison Thimbles RTP is 96%. This is smack-bang on par with the benchmark figure for casino games at 95-96%. Also, Round Circle rates this game as having low volatility. This means that you will win often, however, the winning amount is small.
