In line with the rest of the Betsoft portfolio, The Curious Machine was built with engaging and profitable features that represent different parts of the slot’s theme. Time-travelling free spins rounds with payout multipliers as well as adventurous cash bonus games are both part of the bonuses you’ll get in this slot, while physics-defying vortexes and double-up functions ensure you get more for your money even outside of the extra features. Play this charming 3D casino game on any device you want and get ready to immerse yourself fully into an exciting story and plenty of bonus prizes.
Even if you have no experience in playing slot machines, The Curious Machine should still be easy for you to play. Before you start, just set up your coin value with the control on your bottom-left side and then pick how many lines you want active and how many coins per payline you want to bet. The range of stakes you can play with starts at only 0.01 credits per round and goes up to 150 credits, giving you a variety of bet sizes to choose from.
To see where each payline goes and which symbols pay prizes, you just have to open the paytable with the “view pays” button on top. The slot has 30 active paylines you can pre-select and only seven paying symbols, each giving prizes in coins. The payouts increase when you bet more coins per line and they can range between 10-1,500 coins per sequence with a single coin per line and 50-7,500 coins when betting all five coins per payline. And what’s quite interesting is that you also have a double-up game at your disposal which lets you duplicate any payout you win while playing for real cash by guessing which hand of your robot sidekick hides a coin.
The Curious Machine online slot also comes in a To Go version that you can enjoy on any Android phone or tablet or any device that runs on iOS. This compact version of the game hides the betting and AutoPlay controls inside a separate menu on your top-left while the screen features only two large Spin and Double Up controls.
Payouts in The Curious Machine by BetSoft are given for all sequences of three, four, or five matching symbols on an active payline. To trigger a prize, however, your sequences will need to start at the first reel on the left and stretch towards the rightmost one. For all small payouts you collect, you can use the Double Up game to boost your prizes or wait for the second chance feature to kick in. This feature gives you a free re-spin anytime there’s a chance to complete a five-of-a-kind win, even for sequences that can trigger bonuses.
To win more without paying more, the slot also gives you two time-travelling bonus games. The first is a free spins bonus and it is triggered by three dinosaur symbols on reels one, three, and five. In this feature, you'll travel back in time to play out free spins and win prizes that are boosted by a random win multiplier of up to 5x which is chosen during each new spin. The second feature, on the other hand, is triggered by three time-machine symbols on reels two, three, and four, and it lets you click buttons to travel through different periods and win instant prizes on each new destination.
And when these bonuses aren’t there, The Curious Machine also has a special shuffle feature which is triggered by a vortex symbol on reels two or four. Once this symbol appears, it will create a vortex that rotates the symbols near to it a random number of times, giving you one more chance to collect a win while playing for real cash.

Another medium-variance slot from BetSoft that offers a thrilling presentation, The Curious Machine is a slot for a wide range of punters. This game is a great match for anyone who likes slots that offer consistent returns and more than a few bonuses, but also punters who like playing for pennies per spin for some old-school 1-payline action. With real money prizes that can exceed 225,000 coins per round, there are certainly enough profits to be made in this game. Nevertheless, you should still expect to see a payout that big only on rare occasions, given the high hit ratio of the slot.
If you want an online slot machine that pays better and you are not afraid of more volatile gameplay, we suggest that you try some high-variance games from BetSoft. The Good Girl Bad Girl slot machine gives you a volatility switch and prizes that exceed 1,000,000 credits while the Blood Eternal and Dr. Jekyll & Mr. Hyde slots offer just as immersive a gameplay as The Curious Machine but also much bigger and more volatile payouts. If you want to play these slots for real money or for free, make sure to go and check out some of our BetSoft casinos, where you can also find an abundance of other top slots plus some exciting welcome bonuses!
