Twin Buffalo: Hold and Win Slot by Booming Games

Two persistence meters run side by side in the base game. Buffalo Bounty collects coins and, once triggered, loads extra coin symbols onto the reels to push toward Hold and Win. Buffalo Spins does the same with scatters, feeding the path to free spins. Neither meter's visual fill reflects actual trigger odds - the pots are cosmetic dressing on an RNG event - but the dual-track setup means both bonus routes stay active simultaneously.

The Collect symbol is restricted to reel 5 and pays out the combined value of every coin visible on screen at that moment. Coin values range from 1x up to 250x (Major), so a well-stacked board with a Collect landing on the last reel produces the base game's biggest single-spin payouts outside of triggering a feature.

Free spins guarantee a 3x3 Jumbo symbol on reels 2-4 every spin. A Jumbo Scatter adds 3 extra spins. A Jumbo Coin instantly triggers Hold and Win mid-feature and fractures into 9 individual coins carrying identical values - a single 5x Jumbo Coin becomes nine 5x positions on the Hold and Win grid. Mini, Minor, and Major coin denominations are excluded from Jumbo coins during free spins, keeping the split values modest but frequent.

Hold and Win starts with 3 respins. Each new coin resets the counter to 3. Filling all 15 grid positions awards the 5000x Grand prize. The Mystery Bonus buy (75x) randomly triggers either Hold and Win or free spins, while the Super Bonus (100x) guarantees free spins that include Hold and Win.
