Standard Gamemode
Every game tick (which occurs every 250ms) includes a very small built-in house edge of around 0.05%. This means that over the long run, the platform has a slight mathematical advantage, which is how the game remains sustainable.
It’s important to note that this edge is extremely minimal compared to most traditional casinos or crash trading sites. At just 0.05%, players have a much fairer chance of achieving consistent results while still allowing the platform to operate reliably.
The house edge does not affect any one specific game round in isolation. Instead, it becomes noticeable only over large numbers of rounds, ensuring the game remains provably fair while still maintaining balance between players and the house.
