Sugar Cubes

Sugar Cubes slot title is another awesome cluster pays game with 5x5 reels that use a cascading symbol feature, free spins with a progressive multiplier, clusters, wilds, and special symbols.

Theme and Story Line

The Sugar Cubes video slot is set inside a novelty and dimly lit sweet production factory where a conveyer belt of dice candies are sprayed and sent to the reels so they can stick together so players can get paid via cluster wins.

Graphics, Sounds, and Animations

Relax Gaming has continued its emergence onto the online slots scene with Sugar Cube arguably becoming one of this developer's best designs so far. 

This slot has everything from animations on and off the reels, 3D graphics, a backdrop of a factory that has been masterfully designed, pipes on the side of the reels that spray the dice moving on the conveyor belt as well as give players meters to control their gameplay. Adding to an amazing display of graphics, animations, and player options there is an entertaining and mischievous soundtrack coupled with bubbly sound effects when symbols explode off the reels.

Top Casinos to Play the Game:


Playing Sugar Cubes may seem complex at first especially if you have not played cluster wins slot games before but actually this game is super easy to learn. 

You press the spin button, symbols will drop off the bottom of the reels and new ones will drop in from above - the technical term for this is cascading reels. The idea is to form clusters of symbols between 4 and 16 over the 5x5 grid system. Clusters are formed only when alike symbols are on adjacent positions. 

When a cluster forms on the reels, the symbols in that cluster will explode and the symbols above will drop in (cascade). If any new wins are formed, the cascading reels feature will continue until no more wins are produced. Basically, this feature is similar to a re-spin. 

To determine how much each cluster is worth there is an interactive paytable which makes the game quite interesting. Visit the menu and select the ‘i’ option. Next, scroll down to the area with the ‘Select Dice’, ‘Cluster Size’ slider, and ‘Bet Amount’ slider. You can select the dice symbol 1, 2, 3, 4, 5, or 6 then the size of the cluster and how much you plan to bet – the ‘Total Outcome’ will show the payout amount. 

Finally, gameplay options can be found around the background factory pipework which has various meters on it. Meters can control quick spins on/off, max bet, auto-spins, sound on/off, and spin bet amounts. You can also configure these options using the menu if you are playing on a mobile device with a small screen.

Bonuses and Free Spins

Wild: The wild symbols will substitute for any of the dice symbols by acting as a wildcard thus linking symbols into larger clusters worth higher payouts. 

Magic Symbols: If magic symbols pair on the reels, every symbol ion the same path will be converted into the highest paying symbol (the 6 dice) giving you an automatic cluster win.

TNT Bomb Symbols: When 2 TNT symbol connect all symbols around the TNT will explode giving you a win worth up to a 12-symbol cluster win.

Free Spins: The scatters are the pink and white candy symbols with ‘S’ written on them. Land 2 together for 6 free spins. Each additional scatter attached to the original 2 will give you an extra 3 free spins. During free spins, the below 2 features will be active:

  • Symbol Eliminator: 2 dice symbols are randomly selected every spin. They will be eliminated from the next set of cascading symbols. 
  • Multipliers: Each time you hit cluster win and the reels cascade, a multiplier is applied. The more times the reels cascade, the higher the multiplier will rise.

Bet sizes, RTP and Variance

Bets are set using the menu or via the bet meter on the factory pipework. The minimum spin bet is 0.20 and the maximum is 100.00 per spin. The payouts do not come that often and most wins come via features, however, standard cluster wins are still important to reduce the cost of each spin. Therefore, this is a medium-high variance slot. The good news is Sugar Cubes does come with a higher than usual RTP of 97.06%.


Honestly, the Sugar Cube slot game came as a surprise to many of us here at What a game! If this is what Relax Gaming has to show for itself with its up and coming slot releases then this is one developer that will be held on the same pedal stool as developers such as NetEnt, Play’n Go, and Microgaming. You have to love the interactive paytable and the controls on the pipework that runs through the factory plus of course the gameplay and features are also outstanding!
