Two calculators: the chance to see one staff card, and the Coin cost of specialty gift smoothies.

This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own [Event] My Hello Kitty Cafe(Build) session. It will not click the shop.

Drop probability

Staff pull chance

Estimate the chance of seeing one chosen staff card at least once when every pull is independent. Use the per-character rate from the gacha machine, not the combined chance of a whole star tier.

Chance of the staff you want (%)Gacha pulls

Enter values from your session.

Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.

Independent-pull model only. The community staff list records each 4-star at 1/1100, about 0.0909 percent, with no pity. Change both inputs for any other listed per-character rate. This does not read your account and does not add duplicate-card value.

Material planner

Gift smoothie Coin cost

Work out how many Coins you still need for specialty gift smoothies at the stall price. Enter only the favorite flavor you can actually gift.

Coins per specialty smoothieSmoothies you wantSpecialty smoothies you already have

Enter values from your session.

Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).

Food stalls list specialty gift smoothies at 250 Coins when that flavor is in the daily pair. Vanilla is a different item at 2 Coins and only restores 20 energy, so do not enter it here.

FAQ

[Event] My Hello Kitty Cafe(Build) calculator questions

What do you actually do in My Hello Kitty Cafe?

You serve customers in your own town for Coins, unlock equipment by leveling, hire Sanrio and human staff with Gacha Tix, and raise the cafe star rating by unlocking floors. The shared city is where you shop, claim group rewards, and enter minigames.

Are any gift codes working right now?

No public code list from November 2026 agrees with the others, and the long community archive currently has an empty active section. Try a new string once, exactly as written. If Confirm does nothing useful, treat that copy as already used or expired.

Do I need Gacha Tix to get Hello Kitty?

Hello Kitty is given during the tutorial, including if you skip it. Extra Hello Kitty cards can still come from the gacha at the listed 4-star rate.
