Stakes multiplied by this interval measure gross wagering, not the net cost of obtaining a bonus. Purchase returns above include the complete purchased round and are divided by the ticket price.

How it plays
20 rules screens from the game
Gems and card ranks fill a five-by-three window crossed by 10 fixed paylines. Purple triangle gems top the paytable at 500x the bet for a five-of-a-kind line, ahead of red hexagons at 200x and amber octagons at 100x, and five Jacks or Tens return 2.5x. Only the Crown Scatter and the coins are beyond the reach of the 777 Wild, which substitutes for everything else.
Gold coins carry cash values, and some show MINI or MAJOR instead, worth 10x and 50x the bet. A coin pays nothing by itself: it needs a Collect coin on the same spin, which adds up every value on the screen, jackpots included, whether that spin is an ordinary one or a free spin.
Landing six or more coins together starts Hold and Win. They lock for three respins in which only the empty positions spin, each fresh coin restores the count to three, and covering all 15 positions pays the Grand, shown as FUN 2,000.00 at a FUN 1.00 bet. Free spins can host the feature too.
Three Crown Scatters anywhere return 5x the bet together with 10 free spins at the triggering bet, while four return 25x and five 200x with the same 10 spins; three or more again inside the feature add 10. Through Risk'n'Buy the free spins cost 150 bets and Hold and Win 75, and the same menu holds a Risk Wheel with a x1000 ceiling. Free spins were the one purchase made here and each wheel offer was refused, so the measured return belongs beside the 96.01% RTP of plain play; with Risk'n'Buy the game lists 96.13%. Bets are adjustable between FUN 0.10 and FUN 50, the series stayed at FUN 1.00, and x3500 is the most one round can pay.

Verdict
Most coin spins paid nothing
Major coins came up in 14 of the 10,000 ordinary rounds, 11 times on a base spin and twice in free spins, and none of those 13 met a Collect, so each paid nothing. The only Major that paid sat on the last board of round 8109, a Hold and Win that began on six cash coins, ended with 11 and closed at 98.1x.
Ordinary spins opened Hold and Win 43 times, one per 232.6 rounds, while natural free spins came once per 333.3, and the 34 largest results among rounds without free spins were all Hold and Win. Those 43 rounds averaged 38.41x the stake, and their respins paid 18.50% of all ordinary-series payouts. No board covered all 15 positions; the fullest closed on 14 coins.
The 8 purchases with a Hold and Win inside averaged 173.07x the FUN 1.00 bet, against 128.05x for the other 42, and all 50 tickets at FUN 150 together returned 90.17% of their cost. Natural free spins rounds, 30 of them, paid 29.37% of the series' payouts, from 18.5x in round 2669 to 190.3x in round 6858, whose first free spin alone brought 143.0x.
- Hold and Win came from the base game once per 232.6 rounds, more often than natural free spins at once per 333.3
- A Collect landed on 196 base spins and gathered FUN 958.80, 10.75% of ordinary payouts, with 20.00x at the top
- Round 6858 got 143.0x from its opening free spin and finished at 190.3x
- Seven base-game Hold and Win rounds reached 50x or more, the best 98.1x
- Coins showed on 9,417 base spins, and on 9,178 of them neither a Collect nor Hold and Win paid them
- 226 base spins stopped on five coins, one short of starting Hold and Win
- No respin board covered all 15 positions, so the Grand never paid; the fullest held 14 coins

FAQ
8 questions · answered from the log
Does a Major jackpot coin pay if it lands on a normal spin?
No. A Major coin needs a Collect coin on the same spin or a place on a Hold and Win board; 11 base spins showed one without either and paid nothing for it. Against 9,417 base spins with coins, only 196 carried a Collect and 43 opened Hold and Win.
Between two Hold and Win starts, how many ordinary spins pass?
232.6 on average: 43 starts came in 10,000 ordinary spins at FUN 1.00, and 36 of them had exactly six coins. The median Hold and Win round paid 34.2x the stake.
What was left of the FUN 10,000 demo balance after the ordinary series?
FUN 8,919.10, an 89.19% return against the declared 96.01%. The measured mean's approximate 95% CI, 76.93% to 101.45%, still takes in the declared figure, and no win was ever sent to the Risk Wheel.
Would buying free spins at 150x have paid off?
No. Returns from 50 tickets at FUN 150 came to FUN 6,762.90, 90.17% of what they cost, with FUN 115.40 for the median ticket, or 0.769x the price. Ticket 10 did best at FUN 361.50, 2.41x.
When a Collect coin lands on an ordinary spin, what does it gather?
Every coin value on screen, jackpot coins included, and only on that spin; a Collect with no other coin beside it gathers nothing. The best collections paid 20.00x the stake, in rounds 11 and 7071.
Can six coins during free spins start Hold and Win, and do the free spins carry on?
Yes. The board is played inside the bonus, after which the remaining free spins continue; that happened in 2 of 30 natural bonuses and 8 of 50 purchases, and those 8 tickets averaged 173.07x the FUN 1.00 bet.
Did any Hold and Win board fill all 15 positions for the Grand jackpot?
No. The fullest of the 43 Hold and Win rounds started from ordinary spins closed with 14 of the 15 positions covered; the Grand plaque reads FUN 2,000.00 at a FUN 1.00 bet.
Did Mini coins on base spins usually get paid?
No. Base spins showed a Mini 153 times, and 147 of those left it unpaid; three paid it through a Collect and three opened a respin board with it.
