How to play
Jewel Tumble has no reels and no paylines. A single press of Spin fills a grid six gems wide and five tall, and the grid itself is where the wins happen.
- Pick a bet per spin: 10, 20, 50, 100 or 200 credits.
- Press Spin. Thirty gems fall into place.
- Any three or more matching gems in a straight row or column pay. Diagonals don’t count, and the gems have to sit next to each other in the line.
- Every winning gem shatters. The gems above slide down to fill the gaps, fresh gems drop in from the top, and the new grid is checked again.
The cycle repeats until a grid comes up with no lines. The panel shows Win so far while the drops play out, then the total and the number of drops. Pay table lists every amount at your current bet.
One gem can sit in two lines at once, say the end of a row and the middle of a column. Both lines pay, and the gem shatters once.
Pay table
Line pays, as multiples of your bet, before the multiplier:
| Gem | 3 in a line | 4 | 5 | 6 |
|---|---|---|---|---|
| Ruby | 0.9 | 2.5 | 8.5 | 34 |
| Sapphire | 0.7 | 2 | 7 | 25 |
| Emerald | 0.5 | 1.7 | 5 | 17 |
| Amethyst | 0.3 | 1.4 | 4.5 | 14 |
| Topaz | 0.3 | 1 | 3.5 | 10 |
| Amber | 0.2 | 0.9 | 2.5 | 8.5 |
The grid shape matters here. Columns are only five gems tall, so a 6-in-a-line can only happen across a row. Every gem drops in independently, but they’re not equally common: amber is the most frequent at about 1 gem in 5, ruby the rarest at about 1 in 8.4. That’s why a ruby line pays four times or more what the same amber line does.
Small three-gem lines on a single grid often pay less than the bet. A spin can win something and still come back below what you staked.
The drop multiplier
What separates this game from a plain match-three is the multiplier attached to each drop:
| Grid in the chain | Multiplier |
|---|---|
| First (the spin itself) | ×1 |
| Second | ×2 |
| Third | ×3 |
| Fourth and every one after | ×5 |
All lines on a grid are added up, then multiplied. A ruby 4-in-a-line pays 2.5× your bet on the opening grid, but 12.5× if it forms on the fourth drop. Long chains are where nearly all the large wins come from.
The numbers
A chain of drops can’t be worked out with a formula, because each new grid depends on where the old gems fell. So the return was measured instead, over 4,000,000 simulated spins:
- Return: 96.89%, with a margin of about ±0.09%.
- About 65% of spins pay something.
- On average a spin produces 0.93 paying grids. Most spins stop after one, which means chains reaching the ×3 and ×5 steps are uncommon.
Strategy
Nothing you do changes the outcome. There’s no hold, no gem to pick and no feature to trigger, and the bet size scales every prize by the same factor without touching the odds.
What you can manage is the pace. With about two spins in three paying, Jewel Tumble feels gentle compared with most grid games, but many of those payouts are small fractions of the bet. A low bet gives you more spins to wait for the multiplied chains. Raising the stake after a run of small wins doesn’t make a long chain more likely.
The two sister grids play very differently. Sugar Cluster uses a 7 × 7 grid and pays on touching groups of five or more, so wins are rarer but chunkier. Candy Bazaar pays on eight matching sweets anywhere on the grid and adds multiplier bombs.
