One world on a guest pass, two more with a free account, and every rule set out plainly.
Bubble Tram opens with a guest pass. It asks for no name, email or password: you tick that you are 18 or over and in the UK, accept the terms, and the pass runs for two hours with 100,000 guest coins.
The other two worlds open with a free account, and the form is just four fields — nickname, email address, password, and a tick to say you are 18 or over. No card field, no address, no phone number: nothing on this site costs anything. The account does two jobs. It keeps your coins and progress waiting for your return, and it lets us keep the games for adults. One button on your account page deletes it and everything it holds.
You begin with 100,000 free coins, plus anything won on a guest pass using the same device. Your balance, level and missions travel with you through every world. Coins here are only virtual: nobody can buy, sell, withdraw or exchange them for anything, and no win carries real-world value.
There is no payment page on the site, and no in-app purchases either.
Each world uses five reels and three rows. Wins pay from left to right, starting on the first reel and running along adjacent reels on fixed paylines. Your stake is divided equally between the lines, and the paytable lists values as multiples of the line bet, apart from the scatter, whose pay is based on the total stake. Each line pays only its highest win.
| Feature type | What it does | Worlds |
|---|---|---|
| Tumbling reels | Winning symbols disappear, the others drop down and fresh ones fall in from above. Every fresh win along the chain is worth more: x1 on the original spin, then x2, x3, and x5 on every tumble beyond that. | Lamproom Hoard |
| A multiplier that keeps rising | During free spins the multiplier keeps rising and never falls back before the round ends. | Bubble Tram |
| Wilds that stick and respin | If a paid spin pays nothing but lands a wild, every wild stays put and the rest of the grid spins again for free. | Kelpwood Maze |
| Last-reel respin | When a paid spin with no win shows two scatters, the fifth reel spins once more for free, looking for the third. | |
| Free spins at double pay | The simplest round in the bay: three scatters trigger free spins, and every win inside them pays double. |
Every reel carries a fixed strip of symbols. On each spin your browser’s random number generator chooses an independent random position on every strip. Earlier spins never influence later ones, and nothing adjusts to your balance or to how long you have been playing.
For each world, we find the return, hit frequency and feature frequency by putting that game’s own code through millions of spins, then print them in its paytable. They cover coin play in these free games alone and tell you nothing about any real-money game.
Play Orbit Quest Stack is open only to adults of 18 and over. The games run on virtual coins with no monetary value, which can never be bought, sold, withdrawn or exchanged. You will not find a coin shop or a payment page anywhere here, we offer no prizes of real-world value, and doing well here does not mean you would do well at real-money gambling.
