Tanggu Arithmetic Puzzle
Arithmetic & Speed Challenges
Free · Designed for iPad. Not verified for macOS.
Practice mental arithmetic with Tanggu.
BRAIN TEST CHALLENGE
Start with easy addition. Difficulty advances every 10 correct answers, gradually introducing subtraction, multiplication, parentheses and division. Small and larger numbers are mixed with fewer recent repeats. Multiplication and division grow gradually from small single-digit numbers, with exact integer division.
SPEED CHALLENGE
Solve arithmetic questions in five minutes. Difficulty increases every 10 correct answers.
WATCH AN AD TO CONTINUE
Tap the result score card in either challenge and complete a rewarded ad to continue with the same score and difficulty. Brain gives you 30 seconds; Speed gives you five minutes.
ARITHMETIC TRAINING
Choose a number range and the operations to practice.
HEARTS AND ADS
One heart recharges every 30 minutes, up to five. Starting a game or using Pass costs one heart. Tap the home heart and complete a rewarded ad to receive one heart. Gameplay includes banner ads. Ad availability depends on network and inventory.
RECORDS AND RANKINGS
Separate Brain and Speed online leaderboards and on-device records. Contact / Delete Data lets you confirm a reset of your nickname, local records and your server rankings.
Korean and English supported. Scores and rankings are game records, not medical or educational assessments.
