Gem Blast is a video slot from Endorphina built around gems and mining imagery. It runs on 10 paylines, carries a medium volatility profile and offers a maximum win of 5,000x the stake. This review explains how the game is structured, what its numbers mean for your bankroll, and which safety checks matter before you play for real money.
Gameplay and Features
Gem Blast follows the classic gem-slot template: colourful stones act as the main symbols, and wins are formed along a fixed set of 10 paylines. With a fixed line count, you always know how many lines are in play, so the total stake is easy to understand and track.
Check the in-game paytable for the exact reel layout, symbol values and any special symbols or bonus rounds. Reading it before your first spin is the quickest way to see how wins are actually built.

Math Profile: RTP, Volatility and Max Win
The official published RTP is 96.06%. Over a very large number of spins, the game is designed to return about 96.06 units for every 100 staked, which leaves a house edge of roughly 3.94%. This is a long-run average and says nothing about a single session. Operators can offer different RTP versions of the same game, so confirm the figure in the in-game info screen at your casino.
Volatility is medium, which sits between frequent small returns and rare large ones. In practice you can expect a reasonable mix of modest hits and occasional stronger runs, with swings that are noticeable but not extreme.
The maximum win is 5,000x the stake. That is a theoretical ceiling, and reaching it is very unlikely. For bankroll planning, medium volatility suits a moderate budget split into many small bets, so a quiet stretch does not end the session early.
Fairness, Licensing and Safe Play
Slot outcomes are produced by a random number generator. Independent testing labs such as eCOGRA, iTech Labs and BMM Testlabs review RNG behaviour, check that payouts match the stated RTP, and test game integrity so results cannot be predicted or manipulated.
Before depositing, confirm that the casino holds a valid licence from a recognised regulator such as the MGA or UKGC. A trustworthy operator displays its licence details in the site footer, and you can verify them with the regulator directly.
Gambling is for adults aged 18 and over and should be treated as entertainment, not income. Set deposit and time limits, decide your budget before you start, and stop when it is spent. If gambling stops being fun, organisations such as BeGambleAware offer free support.
