How to play, step by step

Choose how many dragons hide among the 16 chests: more dragons means a higher multiplier per chest, but a dragon tends to turn up sooner.
Enter your stake and start the round. The dragon positions are drawn and locked when the round starts.
Tap chests to open them one at a time. Each safe chest raises the running multiplier.
Press Cash out whenever you are happy, once at least 1 safe chest is open.
Open a dragon and the round ends at once and the stake is lost.

Rules

The board has 16 chests (4x4); you choose 1-10 dragons.
Positions come from a verifiable seed. The order you open chests in does not change your chances, because every position is fixed when the round starts.
1 crown chest is hidden on the board: it is a safe chest that opens the Royal Jackpot wheel.
The multiplier after k safe chests is set so that the average return is the same whenever you cash out.

Paytable and RTP

The table shows the multiplier (stake included) by number of dragons and safe chests opened. For example, with 1 dragon, 1 safe chest pays 0.96× and all 15 safe chests pay 14.4×.

9	43.8%	2.057×	5.143×	14.4×	187×	10,296× (7 chests)
10	37.5%	2.4×	7.2×	25.2×	655×	7,207× (6 chests)

A risk example: with 10 dragons the first chest is safe only 37.5% of the time, but opening all 6 safe chests pays 7,207×. The top multipliers can be capped by the per-round payout limit.

An RTP of 90% is the theoretical average over a very large number of rounds: players get back 90 of every 100 units staked. The rest is 5% site revenue and a 5% contribution to the Royal Jackpot. Each round is random, so a session can land far above or far below the average.

Bet limits

Each game shows its per-round bet range in the game window, and the range can change with the site policy, so no fixed figures are printed here. The lowest stake the site allows is 0.01 USDT.

Royal Jackpot

Every real-money round adds 5% of the stake to the Royal Jackpot and gets a chance at one of its 4 tiers (MINI, MINOR, MAJOR, GRAND). A bigger stake gives a proportionally bigger chance. Demo rounds cannot win the jackpot.

Demo mode vs real money

Demo mode uses free points, not real money, and they cannot be withdrawn. The demo pays more than real play (RTP about 100% versus 90% with real money), so treat it as a way to learn the game, not as a preview of real-money results.

Verify a round yourself

Before you play you see a commitment (SHA-256 hash) of the server seed that decides the results. When you press "Rotate seed", the old server seed is revealed; press "Verify" on the game page and your browser recomputes every round itself. If the hash and the results match, the results were not changed after you played. The full steps are in the fairness guide.

DRAGON'S VAULT uses two HMAC-SHA256 digests (messages clientSeed:nonce:vault:0 and :vault:1), 64 bytes in all, to shuffle the 16 positions with Fisher-Yates. The first positions are the dragons, the next one is the crown.

Frequently asked questions

What is the RTP of DRAGON'S VAULT?

90%, however many dragons you choose and whenever you cash out. The multipliers are computed from the true odds so the average return stays fixed.

When can I cash out?

Any time after at least 1 safe chest is open. If you open a dragon before cashing out, the round ends and the stake is lost.

How many dragons should I pick?

There is no best number: every choice has the same RTP. What changes is the volatility. Few dragons means the multiplier climbs slowly and dragons are rare; many dragons means it climbs fast but dragons come early (with 10 dragons the first chest is safe 37.5% of the time).

Does DRAGON'S VAULT have a demo mode? Do I need to sign up first?

Yes. Open the game page and play the demo straight away, no sign-up needed. It uses free points that are not real money and cannot be withdrawn. The demo pays more than real-money play (RTP about 100% versus 90%), so use it only to learn how the game works.

Can DRAGON'S VAULT results be changed after I play?

The random seed is locked with a SHA-256 commitment before you play and revealed after you rotate it, so you can recompute every result in your own browser. If a result were changed after play, the hashes would not match. See the steps in the fairness guide.
