How to Trigger X-Unlock & Unlocking Rows
X-Unlock is the mechanic that opens locked rows on Buffalo Prime X-Unlock's grid as you play, and triggering it comes down to landing the right symbols on a locked row rather than hitting a separate bonus round. Here's the activation sequence in four steps. For the full mechanical breakdown, including how it feeds the jackpot ladder, see the X-Unlock explainer in the full review.
2. Land the unlock symbols
The right symbol combination on a locked row is what flips it open.
3. Row opens for the session
Once unlocked, that row stays active and starts paying on the next spin.
4. Repeat as more rows open
Each additional unlocked row adds real estate to the same 20 paylines.
How to Trigger Free Spins
Free Spins runs as its own round on top of the base game, giving the Running Wins mechanic extra room to build without touching your regular spin balance. Trigger conditions come straight from the base-game reels.
1. Keep spinning the base game
Free Spins triggers from the standard 4x5 reels, not a separate mode.
2. Watch for the trigger combination
Land the qualifying symbols and the round launches automatically.
3. Free Spins plays out on its own
Wins and Running Wins collection continue without dipping into your balance.
4. Return to the base game
Once the round ends, play drops back to normal spins with any unlocked rows intact.
How to Trigger the Running Wins Bonus
Running Wins is the coin-collection layer riding on the X-Unlock feature. Coin and money symbols carry a cash value shown directly on the reel, and stacking them is how you climb Buffalo Prime X-Unlock's six-tier jackpot ladder toward the Royal Jackpot.
1. Land coin symbols on open rows
Coin and money symbols land on any row that's already unlocked.
2. Check the value on the coin
Cash values print directly on the symbol, no separate multiplier screen needed.
3. Collection feeds the jackpot panel
Coins collect toward the six-tier ladder shown live on screen.
4. Hit a tier to win it
Enough collected value lands you on a jackpot tier, from Mini up to Royal at x10,000 the bet.
How to Use Bonus Buy
Bonus Buy skips straight to a feature round for 100x your stake, instead of waiting on a natural trigger. It's a shortcut, not a separate mode - the feature itself plays out exactly the same either way.
1. Open the BUY panel
Tap the BUY button visible in the game's main interface.
2. Confirm the price
The buy-in costs 100x your stake, deducted as a lump sum from your balance.
3. Drop straight into the feature
You're placed directly into the bonus round, no spin needed.
4. Play it out like a natural trigger
Running Wins collection and the jackpot ladder behave exactly the same as an organic hit.
Some casinos restrict Bonus Buy in certain jurisdictions, so the button may not show for everyone. New to the basic controls first? Start with how to play Buffalo Prime X-Unlock before working through these triggers.
