Tower Rush Provably Fair System
Last updated: April 2026Every round of Tower Rush is cryptographically verified. Learn how the provably fair system works and how you can verify any game result yourself.
What Does Provably Fair Mean?
Provably fair is a cryptographic method that lets players independently verify that each game round was conducted fairly. It removes the need to blindly trust the casino or the game provider -- you can check the math yourself.
Before each round of Tower Rush, the server creates a Hash Code from a Key and a Salt. This Hash is shown to you before the round starts, locking in the outcome. After the round ends, the Key is revealed. You can then verify that the Key combined with the Salt produces the exact same Hash, proving that the outcome was predetermined and not altered during gameplay.
This means neither the casino nor Galaxsys can change the outcome after you place your bet.
How the Hash Code System Works
Step 1: Before the Round
The server generates a Key (random sequence of letters and numbers) and a Salt (secret combination). These are combined to create a Hash Code that's shown to you before the round starts.
Step 2: During the Round
You play normally -- place bets, build floors, cash out. The game outcome is already locked in by the hash. The game determines floors, bonuses, and results based on the pre-generated key.
Step 3: After the Round
The Key is revealed. You can now paste the Key and Salt into the verification checker to confirm they produce the same Hash -- proving the round was fair.
Understanding the Verification Key
The verification key in Tower Rush encodes the complete game result for each round. Here is how to read it:
- Key -- a random sequence of letters and numbers generated by the server.
- Salt -- a secret combination of these sequences used alongside the key to produce the hash.
The key encodes each floor's result, separated by underscores (_). Each floor entry contains its coefficient value, which represents the multiplier for that floor. Special floor types have additional markers:
- Standard Floor: The coefficient value alone (e.g.,
1.31means x1.31 multiplier). - Frozen Floor: An
fappears after the coefficient (e.g.,0fmeans a collapsed floor with freeze protection). - Bonus Temple: The format is
coefficient_BonusResult(e.g.,1.55_3means x1.55 floor with x3 bonus multiplier). - Triple Build: Three coefficient values appear, all greater than 1 (e.g.,
1.31_1.02_1.15for three consecutive floors).
A random sequence of letters and numbers is appended at the end of the key.
Example key:
1.31_0f_1.55_3_1.31_1.02_1.15_TowerRush_ab34def5678This example shows: a x1.31 floor, a frozen collapsed floor, a x1.55 floor with x3 temple bonus, a triple build (x1.31, x1.02, x1.15), followed by the game identifier and random hash suffix.

How to Verify a Game Round
- During gameplay, click the fairness icon (shield) to open the Fairness panel.
- You'll see the Hash code for the current round -- this was generated before the round started.
- Play your round normally -- bet, build, cash out or collapse.
- After the round ends, the Key and Salt are revealed.
- In the "Check Hash Code" section, paste the Key and Salt, then click "Check".
- If the hash matches, the round is confirmed fair -- the outcome was predetermined.
Why Provably Fair Matters for Players
Complete Transparency
Unlike traditional casinos, you don't have to trust the operator. You can mathematically verify every single round.
No Manipulation Possible
The hash is generated before your bet. Changing the outcome after would produce a different hash -- immediately detectable.
Player Empowerment
You have the same verification tools as auditors. Every player can independently confirm game fairness.
