CluePost is a logic deduction game where you help a rural mailman bring order to chaos. Each level is a grid where every row is a category (animals, places, crops...) and every column is a position. Your goal: work out which element goes in each cell using only the clues. You never have to guess — every puzzle has exactly one solution and you can always reason your way to it.
Confirm: when you are sure an element belongs in a cell, press and hold that candidate. The element is locked in and automatically disappears as an option from the rest of the row.
Eliminate: when you know an element does NOT belong in a cell, tap it quickly to rule it out. If you make a mistake, tap the ruled-out candidate to restore it, or use the Undo button.
When only one candidate is left in a cell, or an element has only one possible cell left in its row, the game confirms it for you: that is the deduction chain, and watching it cascade is the best part of the game.
Tip: tap a clue to mark it as solved (it shrinks and fades, but stays there). You can drag clues to reorder them, and press and hold any of them to read what it means in words.
When you tap a level you choose the grid size: 4×4, 5×5 or 6×6. The first levels of each world only offer 4×4, and the larger sizes unlock as you progress. Each difficulty awards stars: in advanced levels, 4×4 gives one star, 5×5 two and 6×6 three. Completing a higher difficulty «fills in» the stars you are missing — you never lose progress by playing the easy one first.
Completing a level pays postage stamps: 2 for a 4×4, 3 for a 5×5 and 4 for a 6×6 (the first time you complete each difficulty). Stamps are spent on the Reveal button, which uncovers one correct cell at random when you are stuck. The Check button tells you whether you are on track or how many mistakes are on the board.
The story follows a rural mailman with an extraordinary head for logic. He starts by sorting out the mess at Don Ramiro's Farm, continues — after an abduction he did not see coming — reorganising Zik-7's alien fleet in The Cosmos, and ends up saving the pharaoh's records in Ancient Egypt. Each world has 200 levels, its own icon categories and story panels that unlock as you advance. And the journey does not end there: more worlds are on the way.
