Diver is where InOut Games began. Released December 2022, over a year before Chicken Road would make the studio famous, it’s a straightforward Aviator-inspired title: a submarine ascends through ocean depths, the multiplier rises, and you cash out before the round bursts. No difficulty levels, no Part Cashout, no triple tracks, no color-coded risk — just the basic rising-multiplier mechanic with an underwater theme.
It’s historically significant as the studio’s genesis. And in 2026, it’s also their worst-value game after Squid Gamebler: 95% return and a x100 ceiling are both below every subsequent release from the studio.
Diver vs Aviator: Same Mechanic, Worse Numbers
This title was explicitly inspired by Aviator. Both use the same core mechanic: a multiplier rises in real time, and you decide when to cash out. The comparison isn’t flattering:
| Feature | Diver (InOut) | Aviator (Spribe) |
|---|---|---|
| RTP | 95% | 97% |
| House Edge | 5% | 3% |
| Max Multiplier | x100 | ~10,000x (operator/casino cap applies) |
| Cost/Hour ($1/bet) | $4.00 | $2.40 |
| Multiplayer | ✅ (per InOut) | ✅ See other bets |
| Casino availability | Limited | 3,000+ casinos |
| Released | Dec 2022 | Nov 2019 |
Aviator wins on every measurable dimension: better return, a much higher ceiling (~10,000x), vastly wider availability. This title’s only distinction is the underwater theme — a submarine rising vs a plane flying. Mechanically and mathematically, there’s no reason to choose it over Aviator.
The Studio: The Evolution From Diver to Now
This game’s value to our analysis is as the starting point for InOut’s evolution. Here’s how every metric improved from their first title to their best:
| Game | Year | RTP | Max Mult | Mechanic |
|---|---|---|---|---|
| Diver | 2022 | 95% | x100 | Basic rising-multiplier |
| Chicken Road | 2024 | 98% | x3.2M | Step-by-step |
| Hamster Run | 2025 | 97% | x1,000 | Triple-hybrid |
| Mine Slot | 2025 | 96–97% | x100 (chest stacking) | Slot/mining hybrid |
| Squid Gamebler | 2025 | 94% | x254 | Triple-track + IP theme |
| MegaBlock | 2026 | 95.5% | x2.9M | Tower building |
From this game to Chicken Road: return improved from 95% to 98%, max ceiling went from x100 to x3,200,000, and the mechanic evolved from basic rising-multiplier to four-level step-by-step with visible probabilities. The studio didn’t iterate on the Aviator format — they invented entirely new game categories. This title is the before; everything else is the after.
The Bottom Line
This is the studio’s origin story — and in 2026, it’s a museum piece. The 95% return, x100 ceiling, and basic mechanic have been surpassed by InOut’s own portfolio on every metric. Aviator does the same thing at 97% with a ~10,000x ceiling. Chicken Road costs half as much per bet with infinitely more gameplay depth.
Play this for historical curiosity. Play literally anything else for value.
⚠️ Responsible Gaming Note: The x100 cap means high multipliers are impossible — but the 95% return still takes 5 cents per dollar bet. Short round duration (10–30 seconds) enables very fast session spending. At 200+ rounds/hour with fast play, costs can exceed $10/hour at $1 bets. If gambling is causing problems, contact GambleAware or the National Council on Problem Gambling.
