InOut Games
The studio behind Jumper
Company History
InOut Games works a niche that larger studios mostly skip: instant and arcade-style casino products sitting beside its HTML5 slots. Jumper is pure decision-based play — no reels, no paylines, no scatter triggers. You choose when to cash out, and the RNG handles the rest.
The studio's approach is mobile-first in a literal sense. Titles like Jumper start as phone games with big buttons and rules you can read in a few seconds, and desktop support follows. That plain-spoken design is the point, not a tagline.
What They Do Best
Instant & Arcade Games
Decision-based titles where your timing shapes the payout. Jumper strips out reels and paylines entirely — it plays like an arcade game first and a gambling product second.
Mobile-Native Design
Portrait layout, touch controls, minimal UI. Jumper is built for one-handed phone play with large targets, and the session math assumes short, quick rounds.

Fairness & Licensing
InOut runs an independently tested RNG across its products, and the model in Jumper is identical in demo and cash play — same probability curve, same 96.00%. Your cashout timing changes your personal result; the underlying odds stay put at every bet level.
Why Jumper?
Jumper strips casino gaming down to its skeleton: bet, risk, decide. No features to learn, no symbols to memorize, no bonus triggers to wait on. At 96.00% RTP with a 30,000x peak payout, the math is fair and the format is honest. Every round is a clean contract between you and the RNG — climb until you're satisfied or fall trying.
