KENO BOOST is an online slot from Flux Gaming with an RTP of 96.00%.
Page updated July 2026
KENO BOOST is not a slot in the traditional sense — it's a number-draw game from Flux Gaming built around the long-running keno format, where players pick numbers from a set range and hope enough of them match a randomly drawn selection. The "Boost" in the name suggests an added mechanic layered on top of the classic keno formula, likely aimed at increasing potential payouts or adding extra draw features compared with a bare-bones version of the game.
For anyone unfamiliar with the format, keno games typically let players choose a set number of spots from a larger pool — commonly between 1 and 20 selections out of 80 numbers, though exact ranges vary by title. Once the selections are locked in, a set of numbers is drawn at random, and payouts are determined by how many of the player's chosen numbers match the draw. It's a simple, low-skill format that appeals to players who enjoy lottery-style games with quick, repeatable rounds rather than the reel-spinning mechanics of a video slot.
KENO BOOST carries a confirmed RTP of 96%, a solid figure for a game in this category and one that compares favourably with many keno variants on the market. As with any RTP figure, this represents the theoretical long-run return calculated across a huge number of rounds rather than a guarantee for any individual session.
Further details on this release — including its specific number range, selection limits, any bonus or boost mechanics, and the available betting range — haven't been confirmed at the time of writing. The most reliable way to get the full picture is to check the in-game paytable and rules screen once the game loads, which will lay out exactly how the boost mechanic works and what stake limits apply.
KENO BOOST is best suited to players who already enjoy the keno format and are looking for a slightly enhanced version of the classic experience, rather than newcomers seeking the visual spectacle of a video slot. Its quick, repeatable round structure makes it an easy game to dip in and out of.
As a keno-style number game rather than a slot, KENO BOOST offers a different kind of play experience built around number selection and random draws, backed by a solid 96% RTP.
