Thirty-eight of my 62 paying spins on Booongo's 3x3 coin machine were a single Black X line handing the 1.00 stake straight back, which is how 290 spins at a stated 95.75% ended 96 credits down. The one Hold and Win, on spin 158, locked its Collect coin and gathered 18x the stake.
The game matrix is 3 reel 3 row. A win needs three matching symbols on an active payline, and the Black X at the bottom of the table pays 1x the stake. It arrives with 5 set paylines. The Red 7 is Wild, lands on all three reels and substitutes for every standard paying symbol, though not for the Bonus or Collect coins.
A spread of wagering choices are obtainable from 0.10 to 55.00. This session played 290 spins at a stake of 1.00 from an opening balance of 1,000.00. A moderate volatility maths model is incorporated alongside an RTP of 95.75%, and max win capacity is limited at 6,000x bet. Those spins returned 194.00 on 290.00 wagered, a session return of 66.9%, and the longest run without a win lasted 15 spins.
In greater depth, it's time to scope out all of the main mechanics and rules... Three Red 7s on a line pay 50x the stake, the Golden Bell 30x, the Golden BAR 20x, the Orange and Purple gems 16x, and the Blue diamond, Green triangle and Red square 4x.
Landing Bonus coins on reels 1 and 3 plus a gold Collect coin on reel 2 during the same spin activates the Hold and Win feature. Paylines switch off for the feature, and only Bonus, Jackpot and Collect coins land on the cleared grid. It grants 3 respins. Outside that trigger, silver Bonus coins landing on reel 1 or reel 3 in the base game fill a meter above the grid, and a full meter also awards Hold and Win.
Landing any coin within the reels during the bonus feature resets the spin count back to 3. The feature ends when the respins run out.
The Hold and Win arrives with a selection of coins. Jackpot coins can land as well, with the Mini worth 25x the stake, the Minor 50x and the Major 150x. They may land on any respin...
Minty’s Expert Conclusion: 66.9% back over 290 spins against a stated 95.75%, and a balance that topped out at 999.00, one credit shy of where it started. More than half the paying spins were a Black X line handing the stake straight back, so the hit counter looked busier than the balance ever felt.
777 Coins can actually activate Hold and Win on any spin, unlike merely purchasing a bonus. In this session it arrived once in 290 spins, on spin 158, when the Collect coin collected 18.00, or 18x the stake, with no jackpot coin landing. That creates that atmosphere of expectation in hope of obtaining bigger wins. That 18.00 was 9% of the 194.00 the session won in total.
All else performs fairly to convention, with Bonus and Collect coins apt to surface. The base game supplied the rest, with 62 of the 290 spins paying, and 38 of those were a single Black X line returning exactly the 1.00 stake. Three locked Collect symbols plus a Grand Jackpot coin are the "Golden Goose" reward to strive for. A Grand Jackpot coin pays 2,000x on its own, and arriving after three locked Collect symbols turns it into the Grand Prize at the 6,000x ceiling.
777 Coins shows forceful when it wishes to be. Over 290 spins at 1.00, the balance never rose above its opening 1,000.00, peaking at 999.00 and ending at its lowest point of 904.00 on the final spin. It nearly seems like a spirited Jack Russell that never fully understands its real dimensions. The biggest single hit was 20.00 on spin 73, a Golden BAR line worth 20x the stake.
