Default return as the yardstick for fast rounds
Instant games are a mixed bag: a coin flip, a ball dropping through pegs, a curve that crashes at some point, and a path of steps where after each one you decide whether to carry on. They share one thing – the studio publishes a theoretical return for them. This ranking therefore orders ten titles from the Dukat.bet lobby by default RTP, the figure the studio gives on the game page.
Ties are broken alphabetically by game name. Status as of 12 October 2026.
The word “default” matters. Most of these pages give no RTP range for operators, but InOut states outright that the casino can adjust RTP, maximum win and bet limits. The version running on Dukat.bet may therefore differ from the table – the rules window inside the game has the final word.
The key does not measure pace, volatility or how often a round ends at zero. And a higher RTP is no promise that you will come out ahead: it is an average over a huge number of rounds that no single person ever plays.
Ten fast games, from 99% to a studio page that disagrees with itself
| # | Game | Studio | Default RTP | Game type | Max multiplier / cap | Source |
|---|---|---|---|---|---|---|
| 1 | Heads and Tails XY | BGaming | 99% | coin flip | 1.98× per win | studio’s official site |
| 2 | Plinko XY | BGaming | 99% | plinko | 1,000× | studio’s official site |
| 3 | Dragon's Crash | BGaming | 97% | crash | 10,000×, cap €250,000 | studio’s official site |
| 4 | HiLo | Spribe | 97% | instant card game | not published | studio’s official site |
| 5 | HotLine | Spribe | 97% | quick prediction game | 1,056× | studio’s official site |
| 6 | Trader | Spribe | 97% | chart-based crash | not published | studio’s official site |
| 7 | Fish Road | InOut | 96% | step game | cap $20,000 | studio’s official site |
| 8 | Penalty Unlimited | InOut | 96% | step game | cap $20,000 | studio’s official site |
| 9 | Big Bass Crash | Pragmatic Play | 95.50% | crash | not published | studio’s official site |
| 10 | Rabbit Road | InOut | 95–95.5% (studio gives different values in two places) | step game | cap $10,000 | studio’s official site |
The money amounts are default win caps stated by the studio; InOut itself says the casino can change them. Roughly 3.5 to 4 percentage points separate the first and last rows – no small gap for instant games.
Mechanics and catches of the ten fast titles
1. Heads and Tails XY
A single coin toss, heads or tails, a 50/50 chance. Every win pays 1.98× the stake, from which BGaming derives a 1% house edge. There is no other maximum multiplier – larger sums only come from repeating rounds.
2. Plinko XY
A ball falls through a pyramid of pegs, and the slot it lands in sets the payout. The studio’s top multiplier is 1,000×, and the game has no other features. Watch the name: the excluded-games list in the bonus terms includes “Plinko”, which is a different title.
3. Dragon's Crash
In the lobby it appears as “Dragons Crash”. The multiplier climbs while the dragon sleeps, and you need to cash out before it wakes; you can hold one or two bets per round. BGaming states high volatility and a €250,000 cap.
4. HiLo
Listed in the lobby as “Hi Lo” under table games, so find it via search. Instead of one card you see three: you call “higher or equal” or “lower or equal” and pick one of the three. After every correct call you can collect.
5. HotLine
A quick game that, according to Spribe, grew out of the esports world, with adjustable autoplay. Wins are capped at 1,056 times the original stake. It carries no tag in the lobby – search again.
6. Trader
A multiplayer chart that rises and falls until it collapses; you can cash out at any point before that. Spribe labels the game provably fair. In the lobby it only carries the Nodemoplay tag, so there is no demo.
7. Fish Road
An underwater path with Easy (24 steps), Medium (22), Hard (20) and Hardcore (15) difficulty. Each step adds to the multiplier until a predator fish eats you. The studio promises to restore an unfinished game for up to 30 days.
8. Penalty Unlimited
A penalty shoot-out in three difficulty levels: after each goal you take the win or shoot again, and one miss wipes the round. The $20,000 cap is the studio’s limit; we do not repeat the huge promotional multipliers that sit above it.
9. Big Bass Crash
A Pragmatic Play crash game, filed under slots in the lobby. The multiplier grows until the fisherman loses his net. The “Cashout 50%” feature banks half the stake while the other half stays in play.
10. Rabbit Road
A rabbit crosses the road for carrots, with four difficulty levels up to Hardcore and a cash-out option at every step. The game page says “up to 95.5%”, a tile on another InOut page says 95%. Hence the range and last place.
Studios and titles left outside the ranking’s gate
The Dukat.bet instant section is stocked by Spribe, InOut, Galaxsys, BGaming, Platipus, Gamzix and Onlyplay, among others. Not every studio, though, provided a figure that could be ranked.
- Galaxsys – we could not load its official website, so we have no studio-page RTP for Turbo Mines, Plinkoman, Crasher, Limbo Crash or Aviabom.
- Platipus and Mascot – their game pages state no RTP.
- Onlyplay, Gamzix and Belatra – left out to avoid repeating titles we cover elsewhere; the same goes for Spribe’s Plinko, Dice, Goal, Keno, Balloon and Mini Roulette.
- Chicken Road variants (InOut) – Chicken Road 2 shows 96% and 95.5% in two places, Chicken Road Gold 95.5% and 98%. With that spread, they stay out.
- Crash Fisher (GameBeat) – there is no official game page.
On the reserve list are BGaming’s Limbo XY and Gift X, both at 97% with a 10,000× cap. Rocket Dice XY has no RTP on the studio page. The entry rules are in the methodology.
Where default RTP stays silent on instant games
The key’s biggest weakness is speed. A crash round or a coin flip lasts a few seconds, so far more money turns over in an hour than on a slot. Even a small difference in percentages then multiplies.
The second issue is volatility. Heads and Tails XY and Plinko XY both sit at 99%, yet the first always pays 1.98×, while the second scatters results from small change to 1,000×. Same price, a completely different ride.
Third: in step and crash games you set the risk yourself – through difficulty, target multiplier and the moment you cash out. How these formats work is explained in our instant games overview.
Model calculation with invented amounts – not Dukat.bet data:
A 1 EUR stake, one round every three seconds, ten minutes of play – that is 200 rounds and 200 EUR turned over. At 99% the theoretical loss is 2 EUR, at 95.5% it is 9 EUR. Over an hour that would be 12 and 54 EUR. The real result, however, can stray from the average by tens of euros either way.
So the number of rounds you play matters more than the percentage.
The fast-game bonus and names on the exclusion list
Fast games come with the Dukat.bet package Instant Bonus – 500% up to 3,000 EUR + 15% Cashback.
Reading the terms (section 2, as of 11 October 2026), you will hit an interesting gap: rule 2.14 says nothing about instant games. Rule 2.15, meanwhile, contains a long list of excluded titles – among them Aviator, Mines and Plinko (from Spribe and other studios), Keno and Mini Roulette. Plinko XY from our table is a different title from Plinko, so check the exact names in the Instant Bonus terms and the excluded-games list.
While wagering, a default maximum bet of 5 EUR also applies (2.7) unless the offer says otherwise. On a phone, where these games are played with one thumb, the overview on the mobile play page helps. Play only from 18 and with a limit set in advance – see responsible gaming for details.
