Bonza Bucks Hold and Win Extreme 10,000 Slot by Booming Games

The Roo Bonus is the shortcut. Whenever value coins land during a base spin, a small chance opens the Wheel of Fortune - one segment triggers the main Hold and Win Extreme round outright, others pay the Mini (25x), the Major (100x), or a sum of every visible coin multiplied by 1x through 5x via the All Coins segments. Free Spins also live on this wheel. None of it is triggered by scatters, none of it is scheduled. The wheel either appears on a coin-landing spin or it doesn't, and that randomness is the game's entire rhythm outside of the 6-coin hard trigger.

Inside the respin feature, only coin symbols appear. Three respins on the meter, counter resets to three every time a new coin arrives, and each coin sticks where it lands. What separates this one from a standard Booming hold-and-win is the board layout: you start with one active 3x5 grid and three locked grids beside it. Landing 9 total coins unlocks the second grid, 18 unlocks the third, 27 unlocks the fourth. Filling any single grid completely - all 15 positions covered - doubles every value on that grid, and that doubling applies to the Mini and Major coins too. A 100x Major on a filled grid pays 200x, a 25x Mini becomes 50x.

Fill all four grids and the Grand Bonus pays 10,000x the bet on top of whatever those doubled coin totals add up to. The game caps at 12,000x, which is where the doubled-grid multipliers plus the Grand payout top out together. There's also an extra coin modifier that multiplies every value on the reels at certain feature phases, which is how runs can escalate past a conservative coin layout.

Visually the game sits in the Australian outback at sunset. Warm orange sky above silhouetted acacia trees, reddish-brown rock formations along the horizon, a wooden reel border with yellow trim. Premiums are full-colour animal portraits - a kangaroo mid-leap (the top pay), a crocodile with its jaws open, an alert fox, an eagle in profile - and the royals J/Q/K/A fill out the low pays in blocky multi-coloured tiles. Three jackpot badges sit pinned across the top: Grand 10,000x in red, Major 100x in blue, Mini 25x in green.

The Buy Bonus is available for a bet-multiplier cost shown in-game, and it guarantees the Hold and Win round on the next spin, skipping the Roo Bonus wheel entirely. If you want to compare the mechanic against the original, Buffalo Hold and Win Extreme 10,000 is the series opener with the same four-grid engine but a different trigger path. Bonza Bucks adds the wheel-of-fortune layer on top.
