Last updated: 10 November 2026
The game
lie.up is a free daily logic puzzle run as a hobby project by Paul Hartmann, Germany. You do not need an account, and you do not pay anything. By using the website you agree to these terms.
Puzzles and availability
New cases are generated automatically every day. Each case is checked by a solver so that it has exactly one answer and can be worked out without guessing. Still, mistakes can happen. We try to keep the site running at all times, but we cannot promise that it will always be available, free of errors, or unchanged. We may change, pause or end the game at any time.
Your progress
Your progress, record and streak are stored only in your browser. If you clear your browser data, switch devices or use private browsing, they may be lost. We cannot restore them.
Fair use
Please do not try to disrupt the website, overload it with automated requests, or get around its security. Sharing your daily result, talking about past cases and making videos about them is welcome. Please avoid spoiling today's cases for others.
Content and copyright
The name lie.up, the game design, the pixel art, the texts and the code belong to the operator. You may not copy the game or substantial parts of it, or publish it elsewhere, without permission. The pixel font Jersey 10 is used under the SIL Open Font License.
Liability
The game is provided as it is. We are liable without limitation for intent and gross negligence, and for injury to life, body or health. Otherwise our liability is excluded to the extent the law allows.
Applicable law
These terms are governed by German law. If you use lie.up as a consumer, this does not take away the protection given to you by the mandatory law of the country where you live.
Changes
We may update these terms when the game changes. The date at the top shows the latest version.
