Casebrook is a picture logic-puzzle game for a parent and child to solve together. Read a short story and its clues, then mark a small picture grid to work out who has which pet, snack or toy. Stories, clues and explanations are in English. On a Slovak device, some case controls use Slovak; the game content is not translated.
How to play
- Tap a box in the grid to cycle it: blank → ✗ → ✓ → blank.
- ✗ means "these two do not go together"; ✓ means "these two go together".
- After you tick ✓, the rest of that row and column get crossed off for you automatically. This can be turned off in Settings, opened from the gear icon at the top of a case.
- A case is solved once every pair of categories has exactly one answer.
How do the clues lead to an answer?
Each case has one solution that follows from its clues. Work through the relationships in the grid together. When you finish a case, a written explanation shows how the clues fit the answer. Casebrook does not offer a hint for the next deduction during play.
Case closed
Once a case is solved, Casebrook shows a short, plain-language explanation of how the clues led to the answer, written for your child to read along with you.
What is free, and what is the one-time unlock
The first 3 cases are free. One optional, one-time purchase unlocks cases 4–15: 12 more cases, for 15 in this edition. There is no subscription and no additional purchase is needed for these 15 cases. The parent purchase area shows the price from your store before you buy. If the price is unavailable, Buy is disabled.
Restoring a purchase
If you reinstall the app or move to a new device, use "Restore purchases" from Home, For parents or the unlock screen. This asks Apple's or Google's own store whether you have already bought the unlock on this account, and unlocks the cases again if so — no new payment is taken. Use the same store and account used for the original purchase. Restoring a purchase returns access to cases. Grid marks, used clues, automatic-cross settings, solved cases and the open case are saved on this device, separately from the purchase. They return when you reopen the app, but are not synced to another device. Undo reverses one move, including only the automatic crosses it created. Undo history ends when the app restarts. Start again asks for confirmation and clears only the current case; it keeps your purchase and your other cases.
Playing offline
The puzzles work offline. Buying and restoring require an internet connection and a store account. The app may also contact the store at launch or when checking the price and your purchased unlock. It does not need an app account and shows no ads.
Why does it ask me a maths question before I can buy or restore?
The parent question protects entry to the purchase offer, each purchase or restore, and links leaving the app. Multiply the two numbers written in English and enter the answer in digits. Three wrong answers pause all parent questions for 30 seconds; going back or restarting does not clear that pause. The app saves the failure count and pause end time, not your answers. This is a parent check, not proof of age. Read the full Privacy policy from Home, For parents or Settings without a purchase or parent question.
The parent check is unavailable
If the parent check reports that it is unavailable, close and reopen the app to try again. A completed check must be saved before it can open a protected action. The free cases and local privacy policy stay available.
Does the app read the clues aloud?
No. Stories, clues and explanations are on-screen English text. There is no voice narration; read them together with your child.
Something in a case seems wrong
Tell us which case (its title is shown at the top of the screen) and what you expected the answer to be, and we will look at it.
