A new Suguru puzzle every day, no ads, and one purchase for everything beyond the starter puzzles. Cifrino is a calm number puzzle for short thinking breaks: logic, not arithmetic. No subscription, no energy bars, no countdown. HOW SUGURU WORKS The grid is split into islands. Fill every island with the numbers from 1 to its size, and equal numbers never touch, not even diagonally. Every puzzle has exactly one solution, so you never have to guess. - An island of three cells holds 1, 2 and 3; an island of five cells holds 1 to 5. - The same number may never sit next to itself, not even on a diagonal. - Given numbers are your first clues, and every number you place rules out options around it. A NEW PUZZLE EVERY DAY A fresh daily puzzle is waiting for you, and a streak keeps track of the days you play. Boards range from 5×5 to 7×7, so one puzzle fits into a coffee break. Five levels take you from Easy through Normal, Tricky and Master up to Extreme. A weekly arrow puzzle adds greater-than clues between cells to the island rules. FROM EASY TO EXTREME Easy boards are a gentle start and teach the basic moves: islands with a single option, neighbors that rule out a number. Normal and Tricky ask you to combine several clues. Master and Extreme ask for longer chains of deductions and careful notes. Pick the level that suits your day, and move up when you are ready. BRAIN TEASERS WITHOUT PRESSURE If you enjoy sudoku, kakuro or other number games, Suguru is the next step: a logic puzzle for adults who would rather deduce than calculate. There are no lives and no ads between the boards. You decide how long you think, and a puzzle you have started stays where you left it. TOOLS THAT RESPECT YOUR THINKING - Notes for candidates, so you see what is still possible. - Hints that name the technique and explain the way to the solution, such as Only place or Island pressure, so you learn the pattern instead of just copying it. - Undo for every move, and a check when you are done. - Numbers or symbols: the same logic in the view you prefer. - Technique school: five short lessons on real boards, open to everyone. - Your record for every level: solved, best time and perfect solves, plus streaks. - Fair scoring: checking never counts against you twice, and 90 points or more is a perfect solve. - A calm new look, a dark mode that follows your system, and layouts made for tablets. - English, German, French, Spanish, Italian and Brazilian Portuguese. YOUR START Today's daily puzzle, five practice boards and the arrow puzzles can be played without buying. Every puzzle you have solved stays playable, and nothing interrupts you while you think. CIFRINO COMPLETE One purchase opens the archive of past daily puzzles, Sunday boards, monthly finales and all levels up to Extreme. It is a one-time purchase, not a subscription, and you can restore it on a new device. OFFLINE AND ACCOUNT No account is needed to play or buy. Practice boards and the puzzles you have already loaded or unlocked stay playable offline; new daily puzzles, buying and restoring need an internet connection. The cloud backup is optional. WHO IT IS FOR For fans of Sudoku, Kakuro and nonograms who like clear rules and a puzzle with exactly one solution. Whether you play one Suguru on your commute or work up through the levels over a few weeks, Cifrino keeps it quiet, tidy and fair: one clear puzzle a day, and a reason to come back tomorrow. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Cifrino Full | $1.99 | one-time | ## Is Cifrino safe?
