# Safe Cracker

Number riddles · 30 levels

Search a rainy noir office for the safe's code.

## How to play

- Tap the glowing things in the office (clock, calendar, receipt, books, sticky note) to look closer.
- Each clue is a tiny riddle that gives one digit. Its shape (● ▲ ■ ◆ ★) shows where the digit goes.
- Tap the safe, key in the digits under their shapes and pull the handle to open it.

Later rooms hide harder riddles: hours between two clocks, days across a month end, change from a receipt, and number puzzles.
