Sudoku meets murder mystery puzzles. Murder Sudoku: Tiny Crimes turns whodunit mysteries into bite-sized logic puzzles. Every case gives you a grid of rooms, a victim, a handful of suspects, and a set of clues. Use deduction to work out where everyone was at the moment of the murder. The rules are simple, the cases are not. No two people can share a row or column, every clue is true, and there is exactly one correct solution. Solve the board and the mystery resolves itself: the suspect left alone with the victim is your culprit. No guessing. No luck. Just clues, logic, and a quiet little crime waiting to be cracked. FEATURES - Sudoku-style row and column deduction, reimagined as detective work - Cozy, hand-illustrated crime scenes full of suspects, rooms, and props - Endless cases, from gentle warm-ups to fiendish expert whodunits - Competitive leaderboards to race other detectives - Pencil notes to track your theories as the case comes together - Pure logic puzzles, every case solvable by reasoning alone - Short, satisfying sessions perfect for a coffee break or a commute - Play fully offline, anywhere - One-time purchase to remove ads. No subscriptions, ever If you love whodunit mysteries, detective games, logic grids, brain teasers, or a clever Sudoku variant, Tiny Crimes hands you a fresh case to crack one clue at a time. Follow the clues. Place the suspects. Find the killer. Can you crack every case?

About

BUZZ Math Challenge

Features
Read full description

BUZZ is the fastest maths reflex game on your phone. One rule, zero mercy: when the number on screen is a multiple of 3 or ends in 7, say "BUZZ" out loud or tap the giant button. Any other number? Stay silent and let it pass. Every round is quicker than the last. You start with 2.7 seconds and end up with barely 1.1. Blink and it's over. WHY YOU'LL KEEP COMING BACK • Voice control: shout BUZZ and the game hears you. No hands needed. • Tap fallback: the button and the number itself are both targets. • Streaks: five in a row doubles your points, ten in a row triples them. • Celebrations: confetti, "ON FIRE" and "UNSTOPPABLE" banners, live NEW RECORD alerts. • Learn as you play: every correct buzz shows you why (27 = 3 × 9). • Lifetime stats: games played, best round, best streak, total buzzes. • Second chance: watch a short ad once per run to keep your score going. • Calm mode: turn off screen shake and flashes in Settings. Quick to learn, brutal to master. Perfect for a bus ride, a classroom warm-up or a shout-off with friends. BUZZ listens through Apple's Speech framework only while a round is running, to detect the word "Buzz". The app stores no audio. You can always play by tapping instead.
