Features
Read full description

Exactly 100 is a casual number game about timing, focus, and quick reactions. The rule is simple: watch the number climb, then stop it when you think it has reached the target. Each round is short, easy to understand, and ready for one more try. Game modes: - Solo 100: Stop the rising number as close to 100 as you can. - Local Quick Press: 2 to 4 players each press once, and the closest player to 100 wins. - Mogu 100: Tap numbered moles and try to make the total exactly 100. - Target Challenge: Aim for a random target such as 37, 50, 64, 88, 100, or 123. Choose from Easy, Normal, and Hard difficulty levels. Music, sound effects, and obstacle effects can be turned on or off in Settings. Local rankings track your best score, perfect stops, streaks, mode records, play counts, and best times for Mogu 100. Game Center leaderboards are not used. It is made for quick solo sessions, family play, and friendly local challenges.
