## What is Kartenwerk?

Kartenwerk is Solitaire as a clean proof sheet — calm, exact, honest.

Every deal is proven solvable. No random dead ends: a solver proves a winning line exists before the deal ships. Printed on the board: “Geprüft lösbar” — verified solvable. Not a slogan, a promise.

• Klondike — free, forever.
• FreeCell, the full statistics archive, and the daily-sheet history — one purchase. No subscription.
• Daily sheet: a fresh, verified deal every day.
• Plays offline. Only the ads need a connection.
• German or French deck — both included.
• Built accessible: VoiceOver, reduced motion, high contrast.

Free play is ad-supported: a short ad between deals, and you can watch one to open a single FreeCell deal. The one purchase removes the ads and unlocks everything. Klondike stays free either way.

## Pricing and in-app purchases

Base price: Free.

**One-time purchases**

| Purchase | Price | Type |
| --- | --- | --- |
| Kartenwerk — unlock everything | $3.99 | one-time |
