Blooket Pack Opening SimulatorOpen unlimited packs with real drop rates — free, no account

Every time you press Open, the simulator rolls a random number and maps it onto the pack's drop table — the same rates shown in our Pack Odds Calculator. A blook with an 18.75% rate wins 18.75% of rolls; a Chroma at 0.05% wins one roll in two thousand. Nothing is weighted in your favor and nothing is rigged against you, so long simulated sessions converge on the exact published percentages.

For packs with rotating Chromas — like the Space Pack's Colored Astronauts — only one Chroma from the rotation is live at a time, exactly as in the real market. The simulator picks one active rotation blook per session, so your simulated Chroma odds match the true single-day rate instead of an inflated combined rate.

The Luck check row compares what you actually pulled against the mathematical expectation for your number of opens. It is the fastest way to build intuition for how streaky low-probability pulls really are: pulling zero Legendaries in 50 opens is not bad luck — it is the most likely outcome for most packs.

Use the simulator when you want to feel the odds. One hundred simulated opens shows you what pack luck actually looks like — streaks of duplicates, dry runs, and the occasional jackpot. It is the honest answer to "what would probably happen if I spent my tokens right now?"

Use a calculator when you want to plan. The main Blooket Calculator gives your exact probability for any token budget, the Chase Calculator tells you the token cost of a 50%, 90%, or 99% shot at a specific blook, and the ROI Calculator ranks every pack by expected value per token.

The two together beat either alone: simulate to set expectations, then calculate to budget. If you are saving for a specific Legendary or Chroma, start with the Token Grinder to plan how fast you can earn the tokens you need.
