Plino: Daily Sudoku Puzzle

Plino is one sudoku a day. The whole world gets the same grid, and when you finish, a slip prints one line of story. DAILY A fresh 9x9 sudoku every day, solvable by logic alone. Notes, undo, and a clock that stops when you leave. Finish and the slip prints, stamped for how cleanly you solved it. YOUR COUNTRY'S BOARD Pick a nickname and your country. Today's Daily finish goes on your country's board, so everyone races the same grid. CASE Whodunits on a floor plan. Place each suspect in a square, one per row and column, until every clue agrees. The culprit is the only person alone in a room with the victim. Six cosy, original cases, starting with a guided first case at Gull Cottage. MARKS Sudoku with objects in place of numbers: keys, parcels, books, and stamps. PRACTICE A drawer of stock grids, easy to hard, for when one a day is not enough. They pay a little XP and never touch the board. AND - XP and levels for a quick finish, and a streak for days in a row - Focus time fills an inkwell and earns hints - New inks and papers as you level up - Lo-fi music and tactile tap sounds, both easy to switch off - No ads, no account, and nothing to buy - Progress stays on your phone Written by Andrew Pickett.
