Aviator RTP and Provably Fair: How to Check a Round Yourself

Aviator’s RTP is 97% as per its provider Spribe which means the house edge is 3% (the game keeps roughly LKR 3 of every LKR 100 you stake in the long run). That is the figure for the game over a very large number of rounds, not for any one session. Each individual round can of course be checked out using the provably fair tool as explained below.

What 97% RTP Really Means

People frequently ask whether Aviator is real and the RTP is the figure that in part answers that question. RTP stands for Return to Player. Think of it this way: if LKR 1,000,000 worth of bets are placed across a massive number of rounds the game will in effect return LKR 970,000 at 97% RTP. The other LKR 30,000 is the house edge. This is a long term average over a very large number of rounds so two things are important to bear in mind:

How Provably Fair Works in Aviator

Aviator’s provably fair system allows you to verify that a round hasn’t been tampered with (rather than just taking the casino’s word for it). It operates in four steps as follows:

  1. Before the round the server will generate a secret seed and will show only the hash of that seed (a fingerprint which is irreversible).
  2. The client seeds of the first three players to bet are added to the server seed.
  3. The combination of the seeds dictates the crash point.
  4. After the round the server seed is exposed and anyone can recompute the result and check it.

This proves the result was fixed prior to the betting having taken place and was not subsequently changed.

Verify a Round Step by Step

  1. Open the round you want to check in the history bar above the game screen. Completed rounds remain in the history bar for a while.
  2. Click the fairness or shield icon adjacent to that round to bring up the full details of it.
  3. Copy the server seed, its hash and all the client seeds that are displayed in the fairness window.
  4. Take the revealed server seed and run it through any SHA-256 tool to verify that the hash that comes out matches the one displayed prior to the round.
  5. Compare the calculated result to the actual crash point of the round. If they match then the round wasn’t altered.

Volatility: Why Results Swing So Much

Aviator is a high volatility game. A lot of the rounds finish at low multipliers and a small number of rounds go very high indeed, the average of 97% being a result of both. The two types of round don’t come in any fixed order so the balance will move in long runs (a number of small losses in a row or a few good rounds in a row). One tells you absolutely nothing about what the next round will do. You can see what an uneven result distribution looks like in practice in the round stats on the home page. As swings are completely normal, set a budget before you play and use bankroll control in LKR to keep it.

Frequently Asked Questions

Can a casino change Aviator's RTP?

Operators can offer different game configurations which will result in different RTPs across sites. Spribe's own published RTP is 97%. Always check the game info panel on the site you're playing on prior to playing as this will show the overall theoretical RTP (97.00%) based on a provably fair algorithm in which each multiplier is pre-determined from the combined server and player seed.

Is Aviator rigged?

Aviator's provably fair system allows you to check each round for yourself so you don't have to take anyone's word for it. The server seed hash is displayed prior to the round and the revealed seed allows you to re-calculate the crash point afterwards.

Does provably fair mean I'll win?

No. Provably fair only proves that a round wasn't tampered with, nothing more. It makes no difference to the 3% house edge and can't in any way make a round more likely to pay out for you. Every round still ends at a random point.
