The TapChamps leveling system (checkpoints) is totally different from the level in a game. It is normal that they have different values.
Each game has its own leveling system which is very different from one game to another. For some casual games, you level up really fast by winning quick levels. For some mid-core games, it takes longer and depends on the player’s experience and so on…
At TapChamps, we wanted to give every game the same chance and we created our own leveling system which depends on the time spent on each game.
