Lucky 8 Merge Up™ at 11croco Casino: what you need to know
BGaming's 6x6 cluster-pays slot uses Merge Up cascades to upgrade symbols across nine levels, with 97.25% RTP and very high volatility.
Cluster wins and symbol merges shape every round
Cascades build your win. Lucky 8 Merge Up is a 6 by 6 grid slot where clusters of four or more touching symbols create wins. When a cluster wins, part of it disappears and the rest upgrades to a higher symbol level, triggering a cascade. The game repeats this process until no more wins form. Released in 2024, it blends cluster mechanics with a unique upgrade system that keeps rounds moving and building.
Is this game right for your bankroll? You'll find this slot suits players ready for long dry spells and occasional large wins. The very high volatility means wins are scarce but can be substantial. It works at stakes from NZ$0.20 to NZ$50 per spin, so both smaller and larger stakers can join. The Free Spins bonus and Chance x2 bet option give you ways to chase bigger moments, though neither guarantees them.
Lucky 8 Merge Up builds on every win. Lucky 8 Merge Up pivots around Symbol Merge and Tumble. When a cluster wins, the symbols that remain don't just stay in place—they upgrade to the next level of the symbol hierarchy. This upgrade happens as part of the same cascade, so one spin can chain multiple wins together. The feature defines how rounds play and why a single spin can run much longer than you might expect.

How do marked cells boost your wins? Land 4, 5 or 6 scatters to trigger 15, 18 or 20 free spins. During the round, winning cells get marked; when a marked cell wins again, a multiplier applies and doubles up to a cap of x128. Multiple marked cells in one cluster add their multipliers together.
Can you skip the wait and buy free spins? Pay 100 times your total bet to buy a free spins round outright. Your next spin after purchase triggers the bonus instantly. You cannot use Buy Bonus while Chance x2 is active.
Boost your chances with Chance x2. Toggle this permanent feature on to raise your total bet by 25 percent, giving you better odds of landing scatters naturally. It stays active across spins until you switch it off. Buy Bonus is locked while Chance x2 runs.
How winning clusters change the grid. The 6x6 grid uses cluster pays: groups of 4 or more same-level symbols touching orthogonally trigger wins. When a cluster wins, part of it vanishes and the rest upgrades to the next level, then cascades until no new wins form.
When bonus rounds arrive is not set in stone
Lucky 8 Merge Up bonus timing stays unknown. A bonus round can arrive on your next spin or take much longer to trigger. No pattern controls when scatters land, so you cannot plan a session around landing free spins.
Why does one session differ so much from the RTP? Your session result depends on what tiles appear and where, not on the RTP. The 97.25% RTP describes long-term results across all players, not your individual session outcome.
Maximum win and what you actually see. The maximum win of NZ$250,000 at the top bet is a ceiling you may never reach. Extremely high volatility means most sessions sit far below that peak.

Buy Bonus feature
Pay NZ$1 000 at your NZ$10 bet to jump straight into free spins on the next spin. This purchase costs 100 times your total bet and skips the base game entirely.
Chance x2 ante bet
Toggle Chance x2 before you spin to raise your bet by 25 percent, taking it to NZ$12.50 at your NZ$10 stake. This lifts your odds of naturally triggering free spins but cannot run at the same time as Buy Bonus.
