Jumpasaurs! is a retro-inspired slot from Jinx Gaming in partnership with Hacksaw Gaming that brings the charm of classic 8-bit platform games to the reels. Set in a pixelated prehistoric world filled with quirky dinosaurs, the game combines nostalgic visuals with modern slot mechanics such as mystery symbols, wild multipliers, and an Extinction Spins bonus feature.
Built on a 5Ă—5 reel layout with 19 paylines, Jumpasaurs! delivers high-volatility gameplay with retro visuals and the potential to win up to 10,000x your stake.
Jumpasaurs! is played on a 5-reel, 5-row grid with 19 paylines. Winning combinations are formed by landing matching symbols from left to right across active paylines.
At the start of each base game spin, 1 to 3 reels become activated, indicated by a dinosaur icon beneath the reel. Only activated reels can reveal the game’s special mystery symbols and bonus effects.
When mystery symbols appear, they can reveal coins, Wilds, multipliers, or Scatter symbols, making each spin unpredictable and full of potential.
Jumpasaurs! embraces a nostalgic 8-bit video game aesthetic, inspired by classic platform games of the past.
The base game takes place in a bright prehistoric landscape filled with trees, mountains, waterfalls, and pixel-style scenery. The dinosaurs themselves resemble charming retro characters reminiscent of old-school arcade heroes.
During bonus rounds, the environment transforms into a darker, more chaotic world filled with volcanoes, lava, and dead forests, symbolizing the extinction event threatening the dinosaurs.
The graphics lean heavily into blocky pixel art, while the soundtrack echoes classic chiptune music, reinforcing the retro gaming atmosphere.
