Gems Gala Spin & Lock™ by Dragon Gaming is a 5-reel, 3-row slot with 50 fixed paylines paying left to right. The game carries high volatility and is described with an average return of 97.00% in the supplied data, while the RTP is also listed at 97.45%.
The main feature is Lock-In, which starts when gems form a line of at least three. Special symbols can lock into place during respins, and each new gem resets the counter. Gems may show multipliers from 1× to 100×, while diamond jackpot symbols can trigger mini, minor, major, or grand jackpot prizes.
Free spins are awarded by bonus symbols on reels 2, 3, and 4. During this round, three scatters add six more free spins and a 5× win, with each spin also boosted by a multiplier based on the number of wilds that land. A demo version is available to play for free and practice before playing for real money.
