Odds and payouts
- RTP (return to player)
- The share of stakes a game pays back over the long run. An RTP of 90% means that, on average, every 100 Diamonds staked comes back as 90. It says nothing about any single round.
- House edge
- What the house keeps over the long run: 100% minus the RTP. STRATEGRA’s casino games have a 10% house edge by default.
- Multiplier
- What a win pays, as a multiple of your stake, stake included. A 2x win on 50 Diamonds pays 100.
- Stake
- The Diamonds you put on a bet or a round.
- Payout
- What a winning bet pays back, stake included, rounded down to whole Diamonds.
- Hit rate
- How often a round pays more than the stake. Many STRATEGRA games are tuned so about 1 round in 5 does.
- Risk level (volatility)
- How spread out the results are. Higher risk means rarer, bigger wins at the same RTP. Spin and Plinko let you choose it.
- Max win
- The most one bet can pay: 250,000 Diamonds by default. No multiplier goes past 1,000x.
- Cash out (in a game)
- Taking your win before the round ends, in Crash, Mines, Coin Flip, Hi-Lo and Tower.
- Auto cash-out
- A target you set in advance: the game cashes you out the moment it’s reached.
- Rakeback
- A VIP perk that returns part of the house edge on your settled bets as bonus Diamonds: stake × house edge × your rate.
Provably fair
- Provably fair
- A way of making results that lets you check each one yourself, from seeds you can see. What provably fair means.
- Server seed
- A secret random value from the house. You see only its hash until you rotate it.
- Client seed
- Your own value, mixed into every result. Change it whenever you like.
- Nonce
- A counter that goes up by one with every bet on a seed pair, so no two bets share an input.
- Hash (SHA-256)
- A fingerprint of some data. It can’t be reversed, and any change to the data changes it completely.
- HMAC-SHA256
- A keyed hash. Game results come from HMAC-SHA256 of your server seed with “client seed:nonce”.
- Commit-reveal
- Publishing a hash first (the commitment) and the secret later (the reveal), so the secret can’t change in between. Prize draws use it.
- Hash chain
- A long list in which each hash is the SHA-256 of the one before. Crash uses one backwards, so every round was fixed before the first.
Diamonds and NHB
- Diamonds
- The currency of STRATEGRA, used for everything in the app.
- Bonus Diamonds
- Diamonds from the welcome bonus, invites, daily rewards, missions and rakeback. They’re for play and can’t be cashed out.
- NHB
- The NHBCoin token and the only money on STRATEGRA. Diamonds are bought with NHB and cashed out to NHB. How to get NHB.

Prize draws
- Ticket
- One numbered entry in a draw. Every ticket has the same chance.
- Free entry
- One free ticket a day for every player, into any draw.
- Cover
- The ticket sales a prize draw needs before its prize is guaranteed: 500% of the prize’s value by default. Below it, the winner gets 20% of sales in Diamonds instead.
- Cash alternative
- What the winner of a covered draw can take in Diamonds instead of the prize itself.
- Diamond Pot
- A draw whose paid tickets make up the pot. One ticket wins 20% of it. Diamond Pots.
