Jumpasaurs!
Jinx Gaming, a rising studio and notable Hacksaw Gaming partner, returns with Jumpasaurs!, a follow-up to the successful Dead Headz. This release reinforces the impression that the developers are avid gamers, taking players back to the blocky, 8-bit era of platform entertainment. Instead of plumbers like Mario, a quintet of cool dude dinosaurs populate this quirky slot, which mixes classic fruit symbols with prehistoric themes. With a solid max win of 10,000x the stake and an “Active Reel” mystery mechanic, it promises adrenaline without the wait, though it lacks the depth of some competitors.
Jumpasaurs! Gameplay and Mechanics
Jumpasaurs! is built on a 5×5 grid with 19 fixed paylines. Between one and three reels are activated on each base game spin, highlighted by a dinosaur. Mystery Symbols landing on these reels can reveal Coin values, Wilds, Wild Multipliers or Scatters. Wild Multipliers range from 2x to 20x and add together on a line. Bronze coins pay up to 8x, silver up to 50x, and gold pays 100x. All Coin values are paid immediately.
Landing one Scatter triggers eight Extinction Spins with all five reels activated, so every Mystery Symbol is collected. Extra Scatters award two more spins. Mystery Symbols during bonus rounds can reveal Coins, Wilds, Wild Multipliers or additional Scatters. For 100x the bet, players can buy direct entry to Extinction Spins.
Jumpasaurs! Theme and Visuals
Jumpasaurs! is a weird but wonderful mashup. Jinx Gaming has thrown curious dinosaurs together with classic fruit machine symbols, so you get grapes and bells sitting next to cartoon dinos on the 5×5 grid. The Jumpasaurs characters perch above the reels, ready to leap into action.
The graphics are bright and clean, with no fancy fluff. You start in a peaceful prehistoric world, then bonus rounds trigger a chaotic shift to volcanoes and lava. The sound is upbeat, and the pace is fast. It just drops you straight in, no waiting around.

Jumpasaurs! Slot Features
Let’s dive into the mechanics behind Jumpasaurs! This slot is driven by the unique Activated Reels system, where dinosaurs bring Mystery Symbols to life with cash prizes, wilds, and bonuses.
Activated Reels
In the Base Game, between one and three reels are activated on each spin, highlighted by a dinosaur at the bottom. This simple mechanic drives everything.
Mystery Symbols
When a Mystery Symbol lands on an activated reel, it can reveal Coins, a Wild, a Wild Multiplier or a Scatter. Mystery symbols landing elsewhere are ignored. During the reveal animation, symbols spin through the space–landing on W gives a Wild, a star gives a Scatter, and a Coin reveals between one and ten Coins. The animation never lands on the question mark.
Coins
Coins come in three variants. Bronze Coins offer values of 1x, 2x, 3x, 5x or 8x. Silver Coins offer 10x, 15x, 20x, 25x or 50x. Gold Coins are worth 100x. When revealed, values are added together and paid as a cash prize.
Wild and Wild Multipliers
Wild Symbols substitute everything except Mystery Symbols, Coins or Scatters. They can be upgraded to Wild Multipliers with values of 2x, 3x, 5x, 8x, 10x, 15x or 20x. When multiple Wild Multipliers hit the same line, their values are added together before being applied.
Scatters and Bonus Game
Revealing a single Scatter in the Base Game awards eight Extinction Spins. During the bonus round, all five reels are activated, so every Mystery Symbol is collected. Extra Scatters award an additional two spins.
Buy Bonus
For 100x the bet, players can buy direct entry to Extinction Spins, landing eight spins with all reels activated.
| Features | Description |
| High-Paying Symbols | Clover, horseshoe, bell, and 7s pay between 25x and 100x the bet for landing 5 matching symbols. |
| Low-Paying Symbols | Grapes, cherries, lemon, orange, and apple pay between 2x and 5x the bet for landing 5 matching symbols. |
