Slingo Rainbow Riches isn’t a slot with a bingo feature bolted on, or a bingo game with slot symbols dressed up. It’s a proper hybrid — spin a reel, match numbers to a 5×5 grid, complete lines to climb a bonus ladder, and unlock the Rainbow Riches features you already know. The Wishing Well, the Road to Riches, the Pots of Gold: they’re all here, earned through Slingos rather than scatter landings. If you’ve played the original slot and wondered what it would feel like built on a different format, this is the answer.
Each game lasts 10 spins. A single reel at the bottom of the screen spins on each play, revealing five numbers. Any number that matches a position on your 5×5 grid is automatically marked. Complete a full row, column, or diagonal line of five matched numbers, and you’ve made a Slingo. Each Slingo advances you one step up the bonus ladder on the left side of the screen. There are 12 possible Slingo lines in total: five horizontal, five vertical, and two diagonal. The last number marked on the grid will always complete at least two lines simultaneously, which is why the paytable shows 11 prize levels rather than 12.
Prizes are only available from 5 Slingos upward. Getting to 3 or 4 Slingos is progress, but it doesn’t pay anything on its own. That’s the game’s defining tension: you’re always a spin or two away from a bonus trigger, and deciding whether to buy extra spins to get there is where most of the decision-making lives.
Four special symbols can appear on the reel during play. The Joker marks any number in the column directly above it on the grid. The Super Joker marks any number anywhere on the entire grid. The Devil is a blocking symbol that prevents a number from being marked. The Free Spin symbol awards an additional spin at the end of the game. Devils appear on the centre reel position only. Free Spin symbols are removed from the reel once extra spins begin.
When your 10 base spins are used up, you can buy additional spins to keep going. The price of each extra spin is shown on the spin button before you commit and is calculated based on your current grid position and the potential prizes still reachable. Prices can exceed your base stake, and they tend to increase with each subsequent extra spin purchased. You can set limits on how many extra spins you’re willing to buy in the game controls. Extra spins are only offered when a bonus game is still achievable on the following spin.
Six bonus games sit at different points on the ladder, unlocking as you accumulate Slingos. Each one is drawn directly from the Rainbow Riches slot series. The ladder also has a strategic dimension: reaching 5 Slingos gives you the option to collect the Wishing Well bonus or keep spinning to try for a higher-value feature further up.
Pick one of three Wishing Wells to reveal a cash prize multiplier.
50 coins spin to reveal multiplier values. There’s a chance to play through up to 4 rounds with increasingly valuable multipliers: x0.5, x1, x2, x5, and x10, giving the feature a progressive feel as it builds.
Three picks from a field of toadstools, each revealing a multiplier of x1–x5 or a fairy. A fairy awards 3 further values. Finishing picks early earns a bonus to the accumulated total: 3 picks remaining quadruples it, 2 remaining trebles it, 1 remaining doubles it.
An upgraded version of Magic Toadstool with 4 picks instead of 3, offering more opportunities to accumulate and trigger the early-finish multipliers.
Spin the wheel to move along the multiplier trail. The wheel segments either advance you along the path or land on Collect, ending the bonus. The trail runs from x8 up to x500.
The same trail format, but all multiplier values are doubled, pushing the top of the path to x1,000. Win amounts from x14 up to x1,000 are available.
Complete the entire grid to trigger the series most recognisable bonus. Twelve pots spin around above a golden arrow. Whichever value lands above the arrow when the pots stop is awarded. Values range from x50 up to x1,000. All bonus game wins are multiplied by your initial stake.
Set your stake, hit Start Game, and the first spin lands automatically. Five numbers appear on the bottom reel; any that match your grid are marked. The grid is fixed at the start of each game and you don’t choose positions or configure anything before play begins. Strategy only enters when Jokers appear, and the game applies a best-strategy rule: Jokers are automatically placed on the position that does most to progress toward a Slingo. The central square gets priority since it contributes to horizontal, vertical, and both diagonal lines. Where multiple positions offer equal value, the placement is random.
The left-side bonus ladder keeps track of your progress throughout the game. The icons next to each line level show which bonus is waiting at that rung. Getting to 5 Slingos doesn’t lock you in. You can collect the Wishing Well prize immediately or spend an extra spin to push further up the ladder toward the more valuable features. That choice repeats at each rung: collect now, or pay for another spin and aim higher. The cost shown on the spin button reflects exactly what the next attempt will cost.
Prizes are awarded when a bonus game completes. The multiplier is applied to your initial stake for that game. The bonus ladder prize levels are as follows:
| Slingos | Bonus | Prize range |
|---|---|---|
| 5 | Wishing Well | Pick 1 of 3 wells |
| 6 | Cash Crop | x0.5 to x10 (4 rounds) |
| 7 | Magic Toadstool | x1 to x5 per pick (3 picks) |
| 8 | Magic Toadstool Red | x1 to x5 per pick (4 picks) |
| 9 | Road to Riches | x8 to x500 |
| 10 | Road to Riches Red | x14 to x1,000 |
| Full House | Pots of Gold | x50 to x1,000 |
All multipliers are applied to your initial stake for that game. There are no symbol-based paytable wins in the traditional slot sense. Every payout comes through completing a bonus game.
A genuinely fun change of pace. Slingo Rainbow Riches takes the Rainbow Riches bonus games out of a slot context and puts them at the end of something you work toward rather than something that just happens to you. The collect-or-push decision at each rung, the escalating extra spin costs, and the familiar bonus games all combine into something that's distinctly its own format. The 95.6% RTP is below the slot equivalents, and sessions that stall below 5 Slingos return nothing, but for players who enjoy a bingo element alongside their features, this is one of the better reasons to try one.
The sessions played for this review landed 3 to 4 Slingos regularly, which is enough to feel close but not enough to pay anything. That’s the tension the game is built around. Once you reach 5 Slingos and the Wishing Well unlocks, you decide whether to collect what’s on offer or spend an extra spin to push toward the Cash Crop or a Toadstool bonus further up the ladder. The extra spin costs start modest and increase with each purchase, so pushing for Road to Riches from a 5-Slingo position means committing to several escalating spins. It doesn’t always work out, but when it does, the higher features are noticeably more rewarding than collecting early.
The Road to Riches Red at 10 Slingos is the standout target for most sessions. Doubling the trail values makes a significant difference on a good wheel run, and the format is familiar enough that fans of the original slot will feel at home the moment the wheel appears. The Pots of Gold at Full House is theoretically the biggest prize but realistically a rare outcome in standard play.
This isn’t a game for players who want fast, reactive slot sessions. There’s waiting involved, and some sessions will feel like a slow grind toward a Slingo count that never quite reaches a bonus. For those who enjoy the rhythm of bingo (watching numbers fall, tracking progress, making deliberate decisions about when to stop) it’s a natural fit. Rainbow Riches fans who know the bonus games well and want to experience them in a different format have a clear reason to try it. A few rounds in free play will quickly show whether the format clicks for you. For players new to the series, the slot versions are a simpler starting point.
The Rainbow Riches slot titles, including Pick ‘n’ Mix and Free Spins, are traditional 5-reel games where features are triggered by scatters landing on specific reels. The experience is reactive; the reels decide what happens and when. This version replaces that with something more deliberate. Progress up the bonus ladder depends on how the grid fills, which extra spins you choose to buy, and which rungs you collect at versus push past. The bonus features themselves are the same, but the path to them is entirely different.
Rainbow Riches Pick ‘n’ Mix (on this site) sits closest in spirit as it lets you pre-select your preferred bonuses before play begins, which shares something of the same player-driven logic. But it’s still a standard slot underneath. For players who enjoy the Rainbow Riches features and want to earn them through something that plays more like bingo than a reel game, the Slingo version has a genuine case to make.
You can buy an extra spin at a higher price if you’re near unlocking a feature and decide to keep going.
The Cash Crop bonus paid out €7.
