BTWZZ puts you behind a rainy-city lost-and-found counter. Owners leave claim tickets. Umbrellas pile up on the rack. Your job is to read the clues, match each canopy to the right person, and stamp the return before the next shower rolls in.
Every case gives you umbrellas on the rack, claim tickets from owners, and a few evidence notes pinned to the board. Nothing moves fast—you compare handles, tag colors, canopy patterns, and where each item was found.
☂
Claim ticket matching
Owners remember specific details: a hook handle with a gold tag, a green striped canopy, mud from the bakery path. Match umbrellas to tickets, then verify your returns with a desk stamp.
📋
Evidence board notes
Weather reports, witness scribbles, and rack positions sit alongside the tickets. Some cases hide a tag clue or add a similar decoy umbrella to keep you reading carefully.
★
Stars and move targets
Each case has a move target. Fewer moves and no hints earn more stars. Perfect returns—every umbrella matched correctly on the first try—count toward your bureau record.
🗺
Case map across the city
Fifty cases split across five neighborhoods, from the morning commute at Station Rack to wind-bent umbrellas at the Harbor Office. Unlock cases in order or replay favorites.
📅
Daily lost item
One rotating case per day with a special modifier—limited moves, no undo, hidden tags, or a perfect-return challenge. Your best star count saves locally for that date.
📖
Practice desk and guide
Short lessons cover color clues, handle shapes, tag colors, location stickers, and condition marks. The bureau guide walks through matching, verifying, hints, and auto-complete.
How a case works
Three steps at the counter
The flow stays the same from Case 1 through Case 50. Difficulty comes from more umbrellas, trickier similar pairs, and tighter move limits—not from new controls to learn.
Read the clues
Open claim tickets and evidence notes. Note canopy color, pattern, handle type, tag color, found location, and condition marks like mud, wind damage, or salt stains.
Match the umbrella
Select an umbrella from the rack, then tap the claim ticket that belongs to it. Repeat until every owner has a match placed on their ticket.
Verify returns
Tap Verify Returns to stamp each match. Correct pairs complete the case and award stars based on moves used and hints taken.
Case map
Five rainy neighborhoods, ten cases each
The case map groups puzzles by where umbrellas tend to turn up. Early cases teach one clue type at a time; later areas combine multiple claims and near-duplicate umbrellas.
Station Rack
Cases 1–10 · Easy to Medium
Morning commuters leave umbrellas by the platform rack. Learn color, handle, and tag matching before the city gets busier.
Bakery Street
Cases 11–20 · Medium
Fresh bread, rain-soaked benches, and curved yellow handles. Location clues and condition marks start appearing on tickets.
Library Corner
Cases 21–30 · Medium to Hard
Quiet reading rooms and green-tagged umbrellas. Formal black canopies and dot patterns show up in the evidence notes.
Garden Event
Cases 31–40 · Hard
Tent tables, ribbon tags, and mix-ups between guests. Multiple similar umbrellas test whether you read every line on the ticket.
Harbor Office
Cases 41–50 · Hard
Dock-side squalls, striped canopies, and salt-stained handles. The captain's umbrella and the tiny travel fold-up close out the map.
Collection and stories
Unlock umbrella styles and owner stories
Completing cases adds styles to your collection—Classic Blue, Yellow Curve Handle, Rose Dot Canopy, Library Green, Harbor Striped, and more. Each unlock ties to a specific case number so progress feels earned.
Owner Stories open after you solve the case they came from: the baker's morning walk, the librarian's rainy note, the harbor captain's striped umbrella, the garden guest mixup at table seven.

BTWZZ runs entirely on your device. Progress saves locally—completed cases, stars, collection unlocks, daily records, and achievement tags. There are no in-app purchases, subscriptions, or third-party ad networks in this version.
If you delete the app or reset local data, your bureau record goes with it. That is by design: your puzzle progress stays on your phone, not on a server somewhere.
