The most complete Blooket pack calculator. Simulate any pack opening, or pick one blook to see exactly what it takes to pull it.
Every Blooket Pack: Costs, Legendary and Chroma Rates
This reference table lists every Blooket pack the calculator covers, with token cost, Legendary and Chroma drop rates, and the named chase blooks. Every rate is drawn from the same validated dataset the calculator runs on. Each pack name links to its full page.

|---|---|---|---|---|---|
| Space Pack | 20 | 0.45% | 0.05% | Astronaut | Colored Astronaut (rotates daily) |
| Medieval Pack | 20 | 1.00% | — | King | No Chroma |
| Wonderland Pack | 20 | 0.30% | — | King of Hearts | No Chroma |
| Bot Pack | 20 | 0.30% | — | Mega Bot | No Chroma |
| Safari Pack | 20 | 0.50% | 0.02% | Lion | Rainbow Panda |
| Aquatic Pack | 20 | 0.70% | — | Baby Shark, Megalodon | No Chroma |
| Breakfast Pack | 20 | — | — | No Legendary | No Chroma |
| Outback Pack | 25 | 0.37% | 0.03% | Sugar Glider | Teal Platypus |
| Pirate Pack | 25 | 0.30% | 0.03% | Captain Blackbeard | Pirate Pufferfish |
| Dino Pack | 25 | 0.30% | — | T-Rex | No Chroma |
| Ice Monster Pack | 25 | 0.35% | 0.15% | Yeti | Ice Slime, Frozen Fossil, Ice Crab |
| Bug Pack | 25 | 0.50% | 0.03% | Butterfly | Blue Butterfly |
| Lunch Pack | 25 | 0.65% | 0.04% | Sandwich | Half a Sandwich |
| Spooky Pack | 25 | 0.65% | 0.06% | Ghost | Super Glider, Skeleton Fish |
| Autumn Pack | 25 | 1.00% | 0.05% | Turkey | Goldfinch |
| Blizzard Pack | 25 | 1.00% | 0.05% | Santa Claus | Chilly Chameleon, Peppermint Bark |
Spooky, Autumn, and Blizzard are seasonal packs. Three one-day packs — Lovely, Lucky, and Spring — sell their Chromas at fixed prices instead of dropping them. The Ice Monster Pack holds the highest combined Chroma rate at 0.15%.
What is the Blooket calculator?
The Blooket calculator is a free tool that turns your token count into exact pack odds and single-blook chances. It runs verified drop rates for every Blooket pack and 227 blooks, validated to total 100% per pack, so you see honest probability before you open anything.
The tool answers two questions players ask most. First, "what will I get if I open this pack with my tokens." Second, "how many packs and tokens do I need to pull this one blook." Most calculators answer only the first.
Every drop rate sits inside a checked dataset. Each pack's five rarity rates add up to exactly 100%, and the Legendary and Chroma rates were cross-checked against each pack's combined rate. That validation is what separates a verified number from a guess copied off a forum.
The calculator connects to the wider site, too. Every blook and every pack links to its own page, so you can move from your odds straight to the full Safari Pack drop rates or a single Rainbow Panda breakdown without losing your place. That structure feeds into how you actually run the tool.
How do I use the Blooket calculator?
You use the Blooket calculator in two modes. Pick Pack Simulator to enter your tokens and see your chase odds for a chosen pack. Pick Single Blook to choose one blook and see the exact packs and tokens needed to pull it.
The two modes cover opposite starting points. One starts with your tokens. The other starts with your goal.
How does Pack Simulator mode work?
Pack Simulator mode shows what your tokens can do against a chosen pack. You pick a pack, type your token amount, and the calculator returns your chase odds for every Legendary and Chroma in that pack.
It also shows expected drops across all five rarities, the full roster of blooks in the pack, and the time to earn your tokens at 60 tokens per minute. At 5,000 tokens, that grind runs about 83 minutes. Each blook in the result links to its own page, so a Lion result connects to the full Lion drop rate page.
How does Single Blook mode work?
Single Blook mode starts with the blook you want. You search any of the 227 blooks by name, and the calculator shows the exact packs and tokens needed at 50%, 90%, and 99% confidence.
It also takes a live token amount and returns your odds for that spend. Hunting Rainbow Panda? Type your tokens and see your chance, then compare it against the 90% target. This mode answers the single-blook question competitors skip, which sets up the next question players ask: which pack gives the best shot.
Which Blooket pack has the best odds?
The Ice Monster Pack has the best Chroma odds at 0.15% combined across three Chromas. For Legendaries, the Medieval Pack and Blizzard Pack give the best odds at 1.0% each. Cheaper packs often carry stronger per-token value for everything below Legendary.
The Ice Monster Pack wins on Chroma chances because it holds three: Ice Slime at 0.08%, Frozen Fossil at 0.05%, and Ice Crab at 0.02%. Added together, that's a 0.15% chance of pulling some Chroma per opening, the highest in the game.
Legendaries tell a different story. The King in the Medieval Pack and Santa Claus in the Blizzard Pack both sit at 1.0%, five times more likely than the rarest standard Legendary. That brings up the opposite end: how many packs the rare targets actually demand.
How many packs do I need to get a Legendary or a specific blook?
The packs you need depend on the drop rate. A King at 1.0% needs about 69 packs for a 50% chance. A Rainbow Panda at 0.02% needs about 3,466 packs for 50%, and 11,512 packs for 90%. Lower rates demand far more packs.
The pattern holds across every chase: the lower the rate, the steeper the climb. A few worked numbers from the verified dataset show the spread.
The Megalodon is the rarest standard Legendary at 0.2%, and it needs about 346 packs for a 50% chance from the Aquatic Pack. The Sandwich at 0.65% from the Lunch Pack reaches 50% in about 106 packs. The Yeti at 0.35% needs about 198 packs for the same target.
Chromas climb hardest. Rainbow Panda at 0.02% reaches 50% at 3,466 Safari Packs, which costs 69,320 tokens. Reaching 90% takes 11,512 packs and 230,240 tokens. Those numbers come straight from the rarest blooks in Blooket data, and they explain why the math behind them matters.
How does the Blooket calculator work out your odds?
The Blooket calculator works out your odds using cumulative probability, not simple division. It applies the formula P = 1 − (1 − p)ᴺ, where p is the drop rate and N is your pack count. Each pack adds an independent chance, so your total odds rise with every opening.
Cumulative probability captures something division misses. A single pack at 0.02% feels hopeless, but 1,000 packs stacks those chances into an 18.13% shot, and 5,000 packs reaches 63.22%.
For the reverse question, the calculator solves for packs. It uses N = ⌈ln(1 − target) ÷ ln(1 − p)⌉ to find the exact pack count for a 50%, 90%, or 99% goal. That's how it tells you 11,512 packs for a 90% Rainbow Panda, rather than the rough estimate most guides print.
Expected drops use the same validated pack rates. Because each pack totals 100%, the count of Uncommons, Rares, Epics, Legendaries, and Chromas you'd expect across N packs lands on solid ground. This honest math also exposes a myth, covered further down, about what those odds promise.
How does resale strategy change your pack count?
Resale strategy stretches your tokens by selling chosen rarities and reinvesting the proceeds into more packs. You choose Keep or Sell for each rarity, set how many reinvestment rounds to run, and the calculator shows the full loop round by round.
Resale sits off by default, so your first result stays honest and assumes no selling. Toggle it on and you control the plan. Most players keep Legendaries and Chromas and sell the lower tiers.
The effect is large. Selling Uncommon, Rare, and Epic pulls from a Safari Pack returns about 10.6 tokens per opening, cutting the effective cost from 20 tokens to roughly 9.4 before reinvestment. The calculator runs that loop until your leftover tokens can no longer buy a pack, then shows every round so the number stays transparent. No competing calculator shows its working this way.
How does the calculator handle seasonal, one-day, and retired blooks?
The calculator handles special blooks honestly instead of forcing fake odds on them. Seasonal packs carry a season tag and still calculate year-round. One-day packs show a guaranteed-purchase card with price. Retired and event Chromas appear as reference cards with their history.
Seasonal packs like Spooky, Autumn, and Blizzard run the normal probability model, with a tag noting their release window. The Space Pack handles its colored Astronaut Chroma by weekday, rotating through seven colors, so the tool shows the correct one for the current day rather than a fixed guess.
One-day packs work differently. Lovely, Lucky, and Spring sell their Chromas at fixed prices around set dates, so the calculator shows a purchase card, not a probability. Retired blooks like the older Snow Globes, and event Chromas like Pumpkin King, never dropped from packs at current rates, so they show as reference with no live odds. Keeping them out of the math protects every other number.
Why a low drop rate never guarantees a pull
A low drop rate never guarantees a pull, because every pack opening is an independent event. Opening 5,000 Safari Packs at a 0.02% rate gives a 63% chance of a Rainbow Panda, not a certainty. Around 37% of players opening that exact count pull nothing.
This corrects the most repeated mistake in Blooket odds content. Many guides claim that a 1 in 5,000 rate means 5,000 packs "guarantees" the blook. The math does not work that way.
Each pack carries the same 0.02% chance, your first and your five-thousandth alike. Previous misses change nothing about the next pull. Dry streaks are expected, not broken odds, which is why the calculator shows rising cumulative chance instead of promising a result. For the full picture, see how to get Chromas in Blooket.
How accurate is the Blooket calculator?
The Blooket calculator is accurate because every pack's rates are validated to total 100% and cross-checked per source. It corrects rates older tools got wrong, including the Safari Legendary at 0.50%, the Pirate Legendary at 0.30%, and the Bug Legendary at 0.50%.
Accuracy comes from a complete record per blook: its rate, sell value, Blook Score, source pack, pack cost, and image. Holding all of it together lets the tool compute odds, expected drops, resale loops, and confidence targets from one consistent dataset.
The corrections matter for trust. Earlier calculators listed a fictional "Snow Globe" Chroma in the Blizzard Pack; the actual Blizzard Chromas are Chilly Chameleon and Peppermint Bark. A small set of seasonal lower-tier rates carry an "approximate" tag, marking honest confidence levels rather than hiding them.

Blooket calculator questions, answered
Is the Blooket calculator free to use?
Yes. The Blooket calculator is free, with no login, no account, and no download. Every calculation runs in your browser, and your tokens and inputs stay on your device.
Does the Blooket calculator guarantee a Legendary or Chroma?
No. The calculator shows probability, not a promise. It tells you the chance and the token budget for a target, but each pull stays an independent event, so no pack count guarantees a specific blook.
How many packs do I need for Rainbow Panda?
Rainbow Panda needs about 3,466 Safari Packs for a 50% chance, and 11,512 packs for a 90% chance. At 20 tokens per pack, that's 69,320 tokens for 50% and 230,240 tokens for 90%.
Which pack has the best Chroma odds?
The Ice Monster Pack has the best Chroma odds at 0.15% combined, spread across Ice Slime, Frozen Fossil, and Ice Crab. The Spooky Pack follows during its Halloween window.
Is a retired blook still obtainable?
No. Retired blooks like the older Snow Globes left the pack pool and no longer drop from packs. The calculator shows them as reference cards with their history, so it never invents odds for them.
Can a Blooket calculator get my account banned?
No. The Blooket calculator is a math tool that never connects to Blooket servers, generates tokens, or changes gameplay. Token generators and cheat scripts risk bans; a probability calculator does not.
