Pariez en devises réellesCrown Coins, a three-reel fruit slot by Endorphina, reads almost entirely through its numbers. Learn them and Crown Coins holds few surprises.
Five lines. Three coins. Four jackpots.
Lines settle ordinary spins. Coins unlock the bonus round, where a sticky Royal Coin gathers prizes from its neighbours, and jackpots ride on the coins themselves, ULTRA at the head.
Below, every number gets its turn: what it does on screen, how it touches your balance, where it stops. Only published information appears here, and when a detail was never released, we say so plainly.
Six numbers that define the slot
- 5 fixed paylines decide each win outside the bonus.
- 3 coins on one spin, across every reel, start the bonus.
- 4 jackpot labels exist: ULTRA, MAX, MID and MIN.
- 1,000x is the multiple ULTRA applies to your total bet.
- 96.16% is the return expected in theory, over the long run.
- 10 doublings back to back mark the Classic Risk Game's limit.

Introducing Crown Coins, a 2024 fruit classic
Since July 2024, Crown Coins has offered a slot pared down to essentials: one story, familiar icons, one bonus.
Bars, bells, sevens and a treasury to build
Bars, fruit, fiery sevens and golden bells fill the reels, while a noble quest runs behind them: pile up gold coins and watch a royal treasury swell.
Who developed the slot
Endorphina built Crown Coins and supplies it to operators, so you meet it in casinos stocking that studio's games.
Three features that shape its character
A Royal Coin that stays put and collects, four jackpot labels and a gamble able to double a win. Free spins never enter the picture.
How to play a five-line round, step by step
Five lines are checked on every spin, and a round needs two actions from you.
Picking an amount per spin
Fix your bet first, within the limits shown; each payout scales with it.
Hitting spin and reading the outcome
Press the button; once the reels halt, wins are credited automatically.
Wild sevens, bars and the five lines
A seven plays the Wild, in the main game alone. It replaces any symbol except special ones, and a line holding three Wilds yields 50x the base bet.
Among regular icons, bars pay most, a trio returning 30x the base bet. Further line values remain unpublished.
Empty spins and the final bonus attempt
A spin without a payline ends quietly. The bonus round carries on until its attempts are spent, then returns you to the standard reels.
Controls around the 3x3 window
Nine reel positions fill the centre, with controls along the edge.
Spin control beside the reel set
The spin control is your main button, set beneath three rows of bars, bells, sevens and fruit.
Stake selector
One selector nudges your bet up or down between rounds, within your casino's range.
Help panel showing rules and return rate
The information icon opens rules, symbol payouts and RTP, worth reading before any paid spin.
Bonus screen with coin cells and jackpot tags
Once the bonus begins, the reels turn into a 3x3 grid where special symbols share space with empty cells. Each jackpot coin wears one of the four tags.
Three-coin entry to the Crown Coins treasury bonus
Three coins or more, arriving together across all reels, open the bonus, officially titled Royal Treasury Bonus Game. Crown Coins pays coin prizes in that round only.
One spin, a coin on every reel
Left, centre and right reels each need a coin on that same result; coins from earlier spins add nothing.
Lucky Time when fewer reels show coins
When coins reach fewer than three reels, Lucky Time Feature may still grant entry, so a near miss is not always lost.
Gold Coin and Royal Coin placement
Gold Coins land on reels one and three only. Royal Coins, source of the slot's name, belong exclusively to the centre reel.
Each coin displays either a jackpot or an ordinary prize, with 15x the total bet as its ceiling.
Four labelled jackpots
ULTRA, MAX, MID and MIN can each turn up. Only ULTRA has a published value, a thousandfold multiple of the total bet; the remaining three stay unquantified.
Comparison table of bonus elements
| Element | Where | Function |
|---|---|---|
| Gold Coin | Reel 1 plus reel 3 | Carries a jackpot or a value as high as 15x |
| Royal Coin | Middle reel only | Holds its cell, absorbing Gold Coin values spin after spin |
| Jackpot tag | Printed on a coin | Awards ULTRA, MAX, MID or MIN |
| Empty cell | Bonus grid | Worth nothing |
| Lucky Time Feature | Spins where coins miss a reel | May still grant entry |
Prizes up to 15x and the collection rule
One regular coin can display as much as 15x the total bet, yet it is the Royal Coin that turns values into money.
Sticky Royal Coin gathering values
A landed Royal Coin keeps its cell until the round closes and, after every bonus spin, takes in whatever Gold Coins show.
Coin prize formula with a ₦6,800 example
Multiply your total bet by the sum of values gathered. Shown as plain arithmetic, never as a forecast:
- Total bet chosen: ₦6,800.
- A Royal Coin picks up Gold Coins marked 15x and 5x.
- Together they make 20x.
- ₦6,800 multiplied by 20 equals ₦140,000.
1,000x for ULTRA
Suppose the total bet were ₦1,700. ULTRA would then equal ₦1,700,000, by straight multiplication. Crown Coins publishes no larger figure.
Random outcomes in each round
Chance alone decides results; no hour, streak or symbol order signals an approaching bonus.
Budget strategy and stake management
Up to ten doublings sit inside the Risk Game, the one moment your decision shapes a round; everything else is money handling.
Bet size measured against your bankroll
Choose a bet small enough to last through many rounds, since bonuses may keep you waiting.
Handling the Risk Game sensibly
With the Classic Risk Game, any payout can be put up for doubling, ten times running at most. One wrong guess erases the whole sum in play, so collecting is often the calmer move.
Personal loss ceiling and exit point
Before starting, write down an affordable loss and a profit level at which you stop, then hold to both.
Decisions following a big bonus
After a generous collection, bank a portion straight away so one strong round is not handed back.
Where planning meets pure chance
Sound habits lengthen sessions but never shift odds; no system makes coins or jackpots more frequent.
Frequent player mistakes on this slot
Four habits empty wallets quicker than bad luck.
- Upping the stake in pursuit of lost money.
- Betting beyond what your budget sustains.
- Sending each payout straight into the Risk Game.
- Continuing because a bonus feels overdue.
Return rate, volatility and ULTRA in Crown Coins
A 96.16% return is an average over countless rounds, not a promise for tonight.
96.16% as the stated figure
Crown Coins carries a published RTP of 96.16%. If your casino's game information lists something else, that listed value governs your play.
Locating the return rate in-game
It sits inside the information panel, next to the rules. Check again at each new casino.
Volatility and how wins are spaced
Volatility measures how unevenly money comes back, not how much. Its level sits in the specification table; no win or bonus frequency is public.
Theoretical cost across ₦1,700,000 wagered
Take ₦1,700,000 bet over many sessions: the arithmetic returns ₦1,600,000 in theory, leaving ₦67,000 as theoretical cost. Any one evening can overshoot or undershoot that mark by a wide margin.
Fairness, randomness and licences
Five lines, one random result per spin: fairness here means no spin borrows from another.
Each spin decided on its own
A coinless run does not enrich the next spin, and a fresh bonus does not push the following one further off.
Facts you can confirm in the game
Rules, RTP and bet limits are printed inside the game, and comparing them with this page takes a minute.
Developer licence and operator licence
Endorphina hands its software to casinos. Protection for you comes via the operator's licence, so find that one.
Free demo and the ₦85 minimum
Studio bets climb from a ₦85 minimum to ₦140,000. The demo costs nothing and shows identical reels.
Demo access through studio partners
Endorphina's partners distribute the free version. Whether a given casino displays it is up to that casino.
Comparing free credits and real stakes
| What changes | Demo | Paid play |
|---|---|---|
| Price | Nothing | Deducted from your balance |
| Winnings | Not paid out | Credited |
| Reels and features | Same | Same |
| Eligibility | No deposit | Adults: 18+, or your jurisdiction's legal age |
Real-money casinos offering Crown Coins
Five checks before depositing save trouble. Crown Coins is listed by operators carrying Endorphina's catalogue, so the choice concerns the casino.
Selection criteria for an operator
A valid licence comes first, then access where you live and bet limits that suit you.
Displayed licence details
A licensed casino states its licence, normally in small type below the main content; no licence, no deposit.
Slot conditions in the welcome offer
Before accepting a welcome package, see how it treats slots. Wagering, excluded titles and bet caps differ between operators.
In-game RTP at that casino
Start the slot and locate its return figure; that is the version this operator runs.
Casino limits and a free version
Compare the casino's bet range with the studio's limits for Crown Coins, and note if a demo is available.
Payment methods and withdrawal rules
Before funding the account, study deposit options, cash-out delays and possible fees.
Casino bonus funds on this slot
Endorphina sets no bonus figures; every promotion belongs to a casino. Each operator chooses the wagering share slot stakes earn, the titles it excludes and the largest bet tolerated with bonus money. Read them first; decline if anything feels vague.
Four steps to a first paid spin
Four short stages lead from sign-up to the reels.
Creating your player account
Use a licensed casino and truthful details. Adults alone may register, meaning 18+ or your jurisdiction's legal age.
Identity documents for KYC
Casinos ask for ID plus proof of address; uploading both early keeps withdrawals smooth.
Funding the account
Favour a deposit option you can also withdraw through, and keep the first top-up within budget.
Search, open and spin from the lobby
Look up Crown Coins in the lobby, launch it, set your bet and spin.
Mobile access on any device
All mobile devices and computers run Crown Coins, and its 3x3 window shrinks neatly onto small screens.
Browser play without installation
Open the casino site in your browser and launch the slot; nothing to download.
Quick launch from a phone's home screen
Browsers on Android and iOS generally allow a page to be saved as an icon, via the browser menu or the share button.
Browser version and network stability
Recent browser software and a dependable signal suffice; if the connection fails mid-spin, casino rules decide that round.
Fruit-machine visuals and coin theme
Golden bells, fiery sevens, bars and fruit give Crown Coins the face of a traditional fruit machine. Gold coins and a royal treasury frame the bonus.
Plus points and minus points
Four jackpots weigh on one side, missing free spins on the other.
Where the format works
Short rules, a sticky Royal Coin giving the bonus a clear target, and ULTRA lending weight to every coin.
Limits of the format
No free spins, few public pay values, and a single failed doubling wipes out a win.
Comparable slots and other Endorphina titles
Endorphina's catalogue reaches well beyond this slot; we compare none of it.
The wider Endorphina catalogue
Lobbies often list games per studio, revealing further Endorphina releases.
Coin-collect and fruit slots elsewhere
Many providers offer fruit icons and coin-collect bonuses; demo mode shows how their rules differ.
Forum and Reddit talk about the slot
We gathered no player comments and reproduce none. Where chance rules every spin, one spectacular win or one grim session proves very little.
Recognition and industry prizes
Published information about Crown Coins lists no award.
