RTP Lucky 8 Merge Up by BGaming is a 6x6 cluster slot with very high volatility and an RTP of 97.25%. The base game uses Merge Up mechanics, where four or more matching number symbols form a paying cluster and then level up into higher-value symbols, creating a progression system across nine symbol levels.
The demo version lets players play for free and practice before playing for real money. Free spins are triggered by 4, 5, or 6 scatter symbols, awarding 15, 18, or 20 spins. During the bonus round, winning clusters generate sticky Cell Multipliers that can rise to x128, with retriggers available if scatters land again.
Additional features include Chance x2 in the main game and a Buy Bonus option for immediate entry to free spins. The slot lists a maximum multiplier of x5000 and a top win of 250,000 euros, with gameplay built around cluster pays rather than fixed paylines.
