About this game
CluePost — Pure Deduction, No Luck
CluePost is a deduction puzzle game where every level has one unique solution. Use clues to eliminate what can't be and confirm what is — just like classic logic grid puzzles, zebra puzzles, and Einstein riddles.
HOW TO PLAY
Each level is a grid of categories and positions. Use the clues to deduce the solution step by step. No luck, no filler: every move comes from the information you already have.
• 8 different types of clues, from simple to those that force you to think two steps ahead.
• 3 grid sizes (4×4, 5×5, 6×6) to choose your level of challenge each game.
• Smart self-confirmation: the game recognizes when a deduction is obvious and solves it for you, so you can focus on what really needs thinking.
1000+ LEVELS, 6 WORLDS
Join the Postman through The Farm, The Cosmos, Ancient Egypt, the Roman Empire, The Vikings, and the Industrial Revolution — each with its own cast of characters, narrative, and unique clue categories.
After sailing with the Vikings, the Postman reaches a brand-new destination: the Industrial Revolution. Factories, inventions, and cities in full transformation bring new clue categories and dozens of fresh levels to solve.
CLARITY MODE
Prefer simple numbers, letters, and colors instead of themed icons? Turn on Clarity Mode in Settings for a more readable experience, especially on larger grids.
100% FREE, NO CHEATS
The entire game can be completed without spending a penny. Ads are always optional and only appear if you choose to watch them in exchange for a reward — they never interrupt gameplay unless you ask for them.
WHO IT'S FOR
If you love Sudoku, brain teasers, cross logic puzzles, or deduction games for adults, CluePost is your next obsession.
