The Tumble Feature Explained
A tumble, also called a cascade, is a feature where winning symbols disappear after they pay, the remaining symbols fall down and new ones drop in from above. If the new layout forms another win, it pays too, and the chain repeats inside the same paid spin until no new win appears.

What a tumble is
On a classic reel slot, a spin stops, pays whatever lines it hit and ends. A tumble slot keeps going. Every winning symbol is removed, gravity pulls the survivors down, empty positions refill from the top, and the game checks the grid again. One stake can therefore pay two, three or ten times in a row. Pragmatic Play calls this the tumble feature; other providers use the word cascade. The mechanic is the same.
On this hub, tumbles run in every Gates of Olympus, Sweet Bonanza and Sugar Rush edition. The line games, meaning The Dog House, Big Bass and Book of Ra, do not tumble.
How a tumble sequence works step by step
- You pay for one spin and the 6×5 or 7×7 grid fills.
- The game evaluates wins under its pay system: eight or more matching symbols anywhere on the scatter-pay grids, clusters of five or more on Sugar Rush.
- Every winning symbol pays and is then removed.
- Remaining symbols fall into the gaps and new symbols drop in to fill the grid.
- The game evaluates the new grid. If a new win appears, steps 3 to 5 repeat.
- When a grid shows no win, the sequence ends and the total is credited.
How scatters behave during the chain is set out in each game's rules, so check the rules screen if you want to know exactly when a free-spins trigger is counted.
Worked example without multipliers
Take Sweet Bonanza at a 1.00 stake. Its paytable, in multiples of the bet, pays grapes 0.4x for 8 to 9, apples 1x for 8 to 9 and bananas 2x for 12 or more.
- First drop: eight grapes win 0.40. They vanish and new fruit falls in.
- First tumble: nine apples now sit on the grid and win 1.00.
- Second tumble: the refill creates twelve bananas, worth 2.00.
- Third tumble: no new win. The sequence ends.
The single 1.00 spin paid 0.40 + 1.00 + 2.00 = 3.40. Without tumbles it would have paid 0.40.
Why tumbles matter so much with multipliers
The real power of the tumble shows up when multipliers are applied to the whole sequence instead of a single win. In Sweet Bonanza free spins, multiplier bombs from 2x to 100x stay on screen until the tumble sequence ends. Then all bomb values are added together and multiply the total win of that sequence.
Continue the example above inside free spins: the same 3.40 sequence with a 5x and a 10x bomb on the grid becomes (5 + 10) × 3.40 = 51.00. If the sequence had produced no win at all, the bombs would have done nothing.
Gates of Olympus works the same way with multiplier orbs from x2 to x500: the orbs are added and apply only if the tumble sequence wins. Gates of Olympus 1000 widens the range to x1000 and Gates of Olympus 2500 to x2500.
How tumbles differ across the hub
| Series | Grid and pays | What tumbles feed |
|---|---|---|
| Gates of Olympus | 6×5, 8+ anywhere | Orbs added and applied to the sequence; in free spins they build a running total multiplier |
| Sweet Bonanza | 6×5, 8+ anywhere | Bombs, free spins only, added at the end of the sequence |
| Sugar Rush | 7×7, clusters of 5+ | Spot marks and doubling multipliers on winning positions |
Sugar Rush: tumbles that paint the grid
Sugar Rush adds a twist. Each position that is part of a winning cluster gets marked. When a second win lands on a marked spot, that spot becomes a x2 multiplier, and every further win there doubles it: x4, x8, x16, x32, x64 and up to x128 on the original and on Sugar Rush Xmas, x1024 on Sugar Rush 1000 and Super Scatter. Long tumble chains are what create those repeat hits on the same spot. In the base game the marks reset after every spin; in free spins they stay for the whole round.
Tumbles inside free spins
Most of the headline wins on tumble games come from free spins, because that is where tumbles meet persistent features. On Gates of Olympus, every winning chain in the bonus feeds orbs into a running total multiplier, so a long chain on spin 12 benefits from everything collected on spins 1 to 11. On Sugar Rush, marks and spot multipliers stay for the whole round, so a chain in the first spins can leave x4 and x8 spots waiting for later clusters. The base game resets all of this after each spin, which is why the same chain is worth far more in the bonus.
Common misconceptions
- "Tumbles are free spins." They are part of the spin you already paid for. The game does not charge again, but the sequence is one outcome of one stake.
- "A long chain means the game is running hot." Each refill is random. A long chain says nothing about the next spin.
- "Tumble slots return more." The chains are already priced into the paytable and the RTP. The paytable is balanced with the chains already in mind.
- "Bombs or orbs always pay." They apply only if the sequence produces a win.
What to watch when you play
Tumble animations can be fast. In a free demo, turn off quick spin for a few rounds and watch the win counter build step by step. It shows you how much of a result comes from the first drop and how much from the chain. On Sugar Rush, watch how marks spread during free spins, since spots with x8 or x16 in the middle of the grid are where large clusters get expensive for the game.
Practical takeaways
- Read a tumble result as the total of the whole chain, not the first win alone.
- In multiplier bonuses, the chain length decides how much the multiplier has to work with.
- In the base game, tumbles mostly turn small hits into slightly bigger ones; the large results come from free spins.
- Budget as usual: tumbles do not change the price per spin.
Frequently asked questions
What is the tumble feature in slots?
Tumble, or cascade, removes winning symbols after they pay, lets the rest fall down and refills the grid from above. If the new layout forms another win, it pays too, and the chain continues within the same paid spin.
Does a tumble cost extra?
No. All tumbles in a sequence belong to the spin you already paid for. The game keeps evaluating the grid until a refill produces no new win, then credits the total.
Which slots on this hub use tumbles?
Every edition of Gates of Olympus, Sweet Bonanza and Sugar Rush. The Dog House, Big Bass and Book of Ra games are line or Megaways slots without tumbles.
How do multipliers work with tumbles in Sweet Bonanza?
In free spins, bombs of 2x to 100x stay until the tumble sequence ends. Their values are added and multiply the total win of the sequence. A 3.40 sequence with 5x and 10x bombs pays 51.00.
What happens to Sugar Rush marks after a tumble?
Positions in a winning cluster are marked. A second win on a marked spot creates a x2 multiplier that doubles with each further win. Marks reset after each base-game spin but stay for the whole free-spins round.
Do tumbles increase RTP?
No. The chains are built into the game's maths and its published RTP. Tumble games simply pay part of their return through repeated wins on one spin.
