Aviator round verifier

Rebuild the multiplier of any finished Aviator round from its seeds. The numbers are worked out on your device.

Two games share the name Aviator and each has its own formula. Pick the one your casino runs. With the other build the hash will not match the round details.

Mind look-alike characters when you type a seed by hand: capital I and small l, zero and capital O.

What you get

The SHA512 hash of the seeds, the number taken from it and the multiplier it produces. If you enter the multiplier the game showed, the tool tells you whether they agree.

Where the seeds are in the game

  1. Open Aviator at your casinoRecent multipliers run along the top of the game.
  2. Click the round you wantA window lists the server seed and three client seeds.
  3. Copy the four values hereThen compare the multiplier with the one in the window.

How to tell the two builds apart

Look at the server seed in the round window. In the Spribe game it is 40 characters of mixed letters and digits. In the Aviator Studio game it is 64 characters, digits and the letters a to f, and the game carries an Aviator Studio logo.

The Aviator formula

The server seed and the client seeds are joined and hashed. The first 13 characters of the hash are read as a number, and that number sets the multiplier. The two builds differ in two places: where the server seed stands in the joined string, and the number the formula is built on.

Aviator by Spribe

hash = SHA512(server seed + client seeds)
h = first 13 hex characters of hash
multiplier = floor(97 × 2⁵² ÷ (2⁵² − h)) ÷ 100

Aviator by Aviator Studio

hash = SHA512(client seeds + server seed)
h = first 13 hex characters of hash
multiplier = floor(96 × 2⁵² ÷ (2⁵² − h)) ÷ 100, never below 1.00

Spribe states an RTP of 97% for its game. The Aviator Studio game states none: about 96% follows from its formula, and that is a figure we derived, not one the game shows.

What the multiplier means in odds is on the Aviator odds and RTP page, written for the Spribe game. To check many rounds in one go, paste them into the bulk bet verifier, and for games with one client seed and a nonce use the provably fair verifier.

Why checking Aviator rounds cannot forecast the next multiplier

Each Aviator round gets its own server seed, and that seed is published only after the plane has flown away. A hundred verified rounds therefore say nothing about round one hundred and one. Apps and chat bots that promise the coming multiplier have no input to compute it from, and our look at crash predictors walks through their claims.

Questions about verifying Aviator

Where do I find the seeds of an Aviator round?

Click any past multiplier in the strip above the game. The window shows the server seed, three client seeds, the combined hash and the result.

Why are there three client seeds?

Aviator takes a seed from each of the first three players who bet in the round and mixes them with the server seed, so no single side controls the outcome.

Can this tool tell me the next multiplier?

No. The server seed of a round is shown only after the round ends. The tool checks finished rounds.

What does the 97 or the 96 in the formula mean?

It is the return the formula is built on. The Spribe game uses 97 and states an RTP of 97%, so 3% is the house edge. The Aviator Studio game uses 96, which works out to a return of about 96% and an edge of about 4%.
