The word explained from the ground up
What is crypto gaming? Two meanings of the same word
The same word is used for a crash round staked in bitcoin and for a game where the characters are tokens on a blockchain. Here we separate the two, and show how a round, a multiplier and a balance in coins actually work.
What is crypto gaming? The answer depends on who is asking. For most people searching for the word it means casino games where the stake is in bitcoin, ether or USDT. For others it means video games built on a blockchain, where items and rewards are tokens. The two have little to do with each other beyond the coin.
This page takes both meanings but spends most space on the first, because that is what the rest of the site is about. You will see how a round is built up, what a multiplier actually works out, and what it means that your balance is held in coins instead of kroner.
Crash: the curve and the stop
What is crypto gaming in the casino sense?
A crypto game in the casino sense is an ordinary gambling game where the stake and the win are in a cryptocurrency. You deposit coins into a casino account, play with them and can ask to have them sent back to a wallet.
The game types recur at nearly every operator: crash games where a curve rises until it stops, plinko where a ball falls through rows of pins, mines with a grid and hidden mines, dice with a figure between 0 and 99.99, limbo with one target value and HiLo where you guess whether the next card is higher or lower. On top of that come ordinary slot machines and live tables, which can also be played with crypto.
House games and studio games
It is useful to distinguish between two sources of the games:
- House games are made or run by the casino itself. They often have simple rules and a built-in check of every round. Rainbet, for example, writes that its Originals games build on provably fair logic, and Bitsler has the crash variant Crash Pro on its list of its own games (both read on 2 September 2026).
- Studio games come from an external game company and are run at many casinos. Aviator from Spribe is the best-known example: the studio gives a 97% return, has a «Play Demo» button on the game page and launched the game in 2019. JetX from SmartSoft Gaming gives a return of 96.2–98.9% and came out in 2018.
The difference matters. The return figure of a studio game is the studio's own figure over very many rounds, and a casino can in principle run the game with other settings. A house game has only the casino's own information to point to. More on the figures is in the explanation of the return and the house edge over time.
How a round works
Most short crypto games follow the same pattern in three steps.
- The stake: you choose an amount in the coin the account is held in, for example 0.001 BTC.
- The outcome: a figure is drawn. In crash it is the point where the curve stops, in dice a figure between 0 and 99.99, in plinko the path the ball takes.
- The settlement: the stake is multiplied by a multiplier, or it is lost.
In games with a provably fair check the outcome is decided before you see it, from a server seed, a client seed and a round number. For Aviator, Spribe describes the hash of the server seed being shown in the settings before the round, and the result being worked out from the seeds with SHA512 when the round starts. How to check a round yourself is in the walk-through of the server seed, the client seed and the nonce.
The multiplier is only arithmetic
A multiplier of 2.47× means the stake is multiplied by 2.47. With 0.001 BTC staked you get 0.00247 BTC back, and the win is 0.00147 BTC.
How high the multiplier is hangs together with the probability. An example with our own figures: in a dice game with a 1% house edge and a 49.5% chance of winning, the payout comes out at (100 − 1) / 49.5 = 2.00×. Lower the chance of winning to 24.75% and the multiplier doubles to 4.00×. The house edge is the same in both cases; only the swings get larger.
Mines: tiles turned one by one
How the most common games look in figures
All the examples here are our own calculations, not figures from a particular casino.
- Crash: the curve starts at 1.00× and rises. Take the stake out before it stops and you get the multiplier at that moment. If it stops first, you lose the stake. More in the guide to the crash round.
- Plinko: with 8 rows there are 256 possible paths. The middle field is reached by 70 of them, so roughly 27.3%, while each outer field is reached by only one path, around 0.39%. That is why the high multipliers sit at the edges. See how the plinko table is built.
- Mines: on a board with 25 tiles and 3 mines, 22 tiles are safe. The chance that the first tile is safe is 22/25 = 88%. A fair multiplier with no house edge would have been 1 / 0.88 ≈ 1.14×; with a 1% house edge it comes out at around 1.13×.
- Limbo: you choose a target value, for example 2.00×. With a 1% house edge the chance of reaching it is (1 − 0.01) / 2 = 49.5%.
- HiLo: if you have drawn an eight in an ordinary deck, there are 24 cards that are higher and 24 that are lower, if the ace counts high and an equal card does not count. The chance is then roughly the same either way.
If you want to see how one of these works in detail, the dice game and the mines board each have a page of their own.
What it means that the balance is held in coins
When you deposit bitcoin, the balance is often held in bitcoin. Many casinos also show an amount in dollars or euro, but that is only a conversion. The value in kroner can change even if you do not play a single round.
Three things are wise to check before a first deposit:
- The rate at crediting. Wild Fortune writes in cl. 11.1 which rate source is used. If nothing is stated, you do not know which rate the deposit is converted at.
- The minimum amount per coin. Bitcasino.io writes in cl. 5 that deposits below the minimum amount are invalid and not refunded. Rocketpot gives 0.001 BTC as the minimum deposit (cl. 10.2).
- The network. Choose a network the casino does not support and the coins are gone — Rainbet says so outright (cl. 7.9).
The number of confirmations on the chain also varies. Rocketpot requires one confirmation for a deposit (cl. 10.5), while Bitcasino.io requires three confirmations before you can ask for a withdrawal (cl. 6.1). Everything about addresses, networks and minimum amounts is gathered in the checklist for deposits.
The other meaning: games on the blockchain
Crypto gaming can also mean video games where part of the economy sits on a blockchain. Characters, weapons, plots of land or cards can be tokens you own in your own wallet and can sell on. Such games are often marketed as «play-to-earn», that is, that you earn tokens by playing.
The most important thing to understand is that this is not casino gaming. The outcome is decided by the game mechanics, not by a draw with a stake and a multiplier. At the same time the value of tokens and items depends entirely on someone wanting to buy them. It can fall sharply, and no table says anything about what it will be tomorrow. We give no advice about buying or selling tokens.
Blockchain games are not discussed further on the site. The rest of the pages are about the first meaning: casino games staked in crypto.
Where you can begin
If you are new, a sensible order is to learn the game before you look at the casinos:
- Read how a round works in the game you are curious about, and work through an example yourself.
- Try a demo version where there is one. Spribe, for example, has a demo button on the Aviator page.
- Look at the casino's terms before you deposit anything: when the identity check starts, whether there is a period for documents, and which caps apply to withdrawals.
- Decide on an amount you can bear to lose, and stick to it.
The last part of point 3 is what the ranking on the list of operators is built on. It carries the clause number and the reading date for every answer, so that you can check the text yourself.
What crypto gaming is not
A crypto game is not an investment. The house edge makes the expected value of each stake a little lower than the stake, whatever the coin. Nor is it a way of profiting from a rise in the rate: if the coin rises while it sits in the casino account, it is the coin that has risen, not the game that has given you anything.
