The iBlooket Calculator is an online tool developed for Blooket players to calculate probabilities of getting specific Blook while opening packs in the game. It helps you to users how likely you are going to get a specific Blook, such as a Chroma, based on the number of tokens you spend and the pack’s drop rate.

Overview
The calculator is hosted on iblooket.com, a fan-made website that provides helpful tools and resources for Blooket players. The tool uses the same drop rate data from Blooket’s official packs to simulate chances of getting rare Blooks. Players can enter how many tokens they have and see the probability of pulling at least one special or Chroma Blook. It is builded by the Youtuber iBlooket. You can check his Youtube channel here.
How It Works
The calculator works using a simple probability formula.
Players input two main values:
- Number of coins or tokens they plan to spend
- Drop rate of the target Blook (for example, 0.05% or 0.0005)
The tool then calculates the chance of obtaining at least one of the chosen Blook after multiple attempts. This makes it easier to understand how rare a Chroma or Legendary Blook truly is and how many tokens may be needed on average.
