Jumper uses SHA-256 hash verification to prove every round outcome was determined before you bet. The server seed is published in encrypted form before each round and revealed after, making manipulation mathematically impossible.
Open the Provably Fair Settings dialog from the hamburger menu to copy current client seed (e.g., 22fb2c5c477b67c5) and server seed SHA-256 hash for independent verification.

Choose your risk level, receive 3-10 randomized free spins, and watch the alien automatically climb to the maximum safe multiplier on each spin. All multipliers accumulate into total win.

All difficulty levels
The platform your alien stands on displays its multiplier in acid green (1.36X) instead of cyan blue. This color-coded system instantly shows your current multiplication factor. Upcoming platforms remain cyan until you land on them.
Accessibility note: Character position is the primary indicator, not color. Colorblind users identify the active platform by seeing the alien standing on it.
The yellow CASHOUT button appears during active rounds, showing exact win amount in real-time. Conservative strategy: cash out after reaching 5-10x on Easy. Aggressive strategy: climb toward 100x+ on Medium/Hard, accepting higher fall risk for exponential rewards.
Malfunction voids all pays and plays. Always verify game state before major decisions.
Jumper immerses players in a dark riveted spacecraft interior resembling a futuristic mining shaft. Each platform is a horizontal metal rectangle with four corner rivets, held aloft by two rocket nozzles blasting yellow-orange flame. The character is a chubby gray alien with enormous black eyes and a backwards green baseball cap, designed in cute Pixar-style proportions.
Neon lime green, glowing cyan blue, deep space navy, industrial metal gray, banana yellow lightning, vivid purple (Medium), bronze orange (Hard)

Traditional slots force you to watch reels spin. Jumper hands you the GO button and CASHOUT button simultaneously. Every second you choose: secure current profit or risk everything for the next platform. This active decision-making transforms passive gambling into strategic risk management.
The provably fair system eliminates trust requirements. You verify the math yourself using published SHA-256 hashes. No black-box RNG. No hidden manipulation. The server commits to outcomes cryptographically before you bet, then proves it didn't cheat afterward.
One game engine, three completely different risk profiles. Easy mode offers calm 40-step climbs to 62x. Hard mode compresses into 35 brutal steps reaching 190,000x. Same interface, radically different mathematical volatility curves.
