Provably fair verification lets anyone independently recompute a game's result from its server seed, client seed and nonce - confirming the casino could not have altered the outcome after the bet. Browse all casinos & games
Stake Dragon Tower is a row-by-row climb where each level hides one or more eggs among the tiles. The safe-tile positions on every row come from HMAC-SHA256 over your server seed, client seed and nonce - fixed before you pick a single tile. Your chosen difficulty, from easy to master, sets how many tiles per row are safe.
Because each row's layout is locked by the seed pair, the whole tower is reproducible from the same inputs. The hashed server seed is the casino's commitment; once revealed on rotation, anyone can rebuild every row and confirm no tile moved after the bet.
Harder difficulties have fewer safe tiles per row, so each step pays a bigger multiplier but is more likely to end the climb. The fair multiplier per row is the inverse of the safe-tile probability, minus a 1% house edge, giving an RTP near 99%. Multipliers compound up the tower, so deep climbs pay steeply but become increasingly unlikely.
| Difficulty | Safe tiles per row / behaviour |
| Easy | Most tiles safe - small steps, low bust risk |
| Medium | Balanced steps and risk |
| Hard | Fewer safe tiles - bigger steps, more busts |
| Master | Fewest safe tiles - largest per-step multiplier |
| House edge | ~1% (RTP ~99%) |
Every row is an independent seed-driven draw, so there is no learnable pattern to the safe tiles - the only real choices are difficulty and how high to climb before cashing out. Easier modes grind small, reliable steps; master mode swings for large per-step multipliers and busts often. The verifier proves a climb was honest, not which tile is safe next.
If you play, set a target row and a difficulty before you start, and cash out when you reach it rather than always pushing one row higher. Higher difficulty raises both reward and bust probability on every step, so treat the difficulty table above as the real risk curve.
No. Each row's safe tiles are locked to your seed pair and nonce before you climb, and this verifier rebuilds them from the revealed server seed. A match proves nothing moved.
Not in advance. The layout uses the hidden server seed, so it cannot be known until seeds are rotated. This tool checks completed climbs only - any predictor is a scam.
Master has the fewest safe tiles per row, so it pays the largest per-step multiplier at the highest bust chance. The house edge is ~1% across difficulties.
Each row's multiplier is the inverse of that row's safe-tile probability, minus a 1% edge, and the steps compound as you climb.
No. The ~1% edge is the same on every difficulty; harder modes only raise the per-step multiplier and the bust risk together.
Rotate seeds to reveal the server seed, paste it with your client seed, nonce and difficulty above, and compare the rebuilt rows to your game.
