Crash and instant games, built in-house
A crash game, one-strike instant games, cash-out games, a pick-and-cash-out party game, a multiplier ladder, a multiplier walk, a risk-tier launcher and an arcade-style chase: sixteen originals in total, each with four simulated RTP models and provably-fair verification on every round.
Short rounds, high frequency, no lobby fatigue
Instant games earned their lobby placement by being legible. A player understands a rising multiplier in about two seconds, and the decision — cash out now or hold — is the entire game. There is no paytable to study and no feature to unlock.
That legibility is why the format travels so well into crypto-native and mobile-first audiences, and why it sustains session lengths that slots often do not. It also makes the math unusually easy to explain to a regulator: one decision, one distribution, one cash-out curve.
Slotty Labs builds these formats first-party. The titles are original, the engine is the same one that runs the slots, and the evidence package is identical across the catalog.
- Four RTP models — 92 / 94 / 96 / 97%, each separately calculated and separately simulated.
- 10,000,000-round Monte Carlo per variant, verified to within ±0.5% of theoretical RTP.
- Provably-fair commit-reveal on every real-money round.
- Server-authoritative outcomes with max win enforced server-side.
- Desktop and mobile HTML5, demo mode included.
- Deterministic replay of any round from its event log.
Fourteen instant games, eight formats
One engine behind them and the Slotty Slots and Popworks video slots: same RNG, same evidence format, same integration path. Adding the second title after the first is configuration, not a new project.
Shots — crash game
A regular knocks back shots while the multiplier climbs on a fixed curve: 2× in about 5 seconds, 100× in 32. Cash out any time or set an automatic cash-out; if the regular goes down first, the stake is lost. High volatility, 1,000× max win.
Shatter — one-strike instant game
Pick a fracture mode and strike the glass panel once: every piece that falls into the tray pays the multiplier token on it, one result in about a second. Players choose their volatility, from Controlled to Extreme, up to 316.55×.
Strike — match-strike instant game
Pick Steady, Bold or Long shot and strike the match: the flame sets the return across eight levels, from a 0.20× Fizzle to a 50× Wildfire, in under a second. Every setting returns the same RTP.
Overload — one-surge instant game
Pick Spark, Surge or Meltdown and press OVERLOAD: current races to five collectors, every collector it reaches pays, and three purple seals set off a Reactor Breach — one result in about a second, up to 500×.
Ricochet — physics shooting instant game
Pick Tight, Scatter or Wild and fire once: pellets ricochet off reflectors, every prize plate hit adds to the return, a red hazard wipes the shot, and matching badges unlock bonus volleys up to 215.30×.
3D City: Neighborhoods — instant city builder
Pick a plot and press BUILD: one draw decides the neighborhood, a construction scene raises it on the plot, and its multiplier sets the return, from green beginnings up to a 250× Metropolis. Medium volatility.
Red District — multiplier ladder
Pick a window and a very confident tourist goes in: each good visit climbs one of eight steps up to 10.50×, a comic mishap ends the round. Cash out between visits. Adult (18+) theme, medium volatility, 10.50× max win.
Wild Stride — stilt-walking cash-out
Drag a stilt and plant it: every step that holds multiplies the total, and the balance meter turns the first two missteps into a wobble or a stumble instead of a fall. A wild stride can pay ×100 in a single step. Collect any time, up to 1,000× (100× by default).
Peak Rush — downhill ski cash-out
Jump the rocks and ravines yourself, backflip for double, triple or quadruple coins, and bank whenever you like before you bail. Every clean landing grows the multiplier, up to 500×.
Pass the Jay — pick & cash out
Ten guests, one undercover cop. Stake once, pass the joint guest by guest and climb a 9-rung ladder, cashing out any time before the cop ends the round. Every stopping point returns the selected RTP. Medium volatility, up to 9.7×.
Safe Smash — cash-out
Every hit on the safe pays instantly and cracks it a little further, toward a 5×–25× jackpot. A hammer break takes back the round's winnings, so every swing is a decision. High volatility, 50× max win.
Bit Key Rush — cash-out
Crack a 12-character key one character at a time while an FBI trace closes in. Every correct character pays instantly, and a bust never takes back what was already paid. Very high volatility, 500× max win.
Katapuuult — risk-tier launcher
Pick safe, medium or risky and the catapult fires the rock to the drawn result, collecting bonuses on the way. Every tier returns the same RTP. Medium volatility, 60× max win.
Fox'n Flock — arcade-style chase
Steer the fox, catch goats and bank the pot at the catch target. The whole run is drawn at the bet, so reflexes and connection speed never change the payout. High volatility, 100× max win.
Three layers of proof on every round
Instant games live or die on player trust — the format is so simple that any suspicion of manipulation is fatal. The answer is verification the player can run themselves.
A standards-based RNG
NIST SP 800-90A Rev. 1 HMAC-DRBG (SHA-512, 256-bit security strength) with multi-source entropy and continuous statistical self-tests based on NIST SP 800-22.
Simulated, not asserted, RTP
Every variant is verified across 10,000,000 fixed-seed rounds and lands within ±0.5% of its theoretical model. The written model ships with the simulation output.
Provably fair commit-reveal
SHA-256 seed committed before the bet, revealed after, verifiable by the player on a public page without trusting the operator or the studio.
