Make Ten – 4 Numbers to 10
Quick arithmetic puzzle
Free · Designed for iPad. Not verified for macOS.
Make 10 from four numbers. That’s the whole puzzle.
You get four digits from 1 to 9. Use all four, each exactly once, with + − × ÷ and parentheses so that the result is 10.
■ The only rules
• Use all four digits, each exactly once
• + − × ÷ and ( ) are free to use
• Reach 10 and you’re right
For example, with 8, 4, 2, 4: 8 + 4 − 4 + 2 = 10.
■ Every puzzle can be solved
Only combinations that can make 10 are dealt. You will never waste time on a hand that had no answer.
■ Build the expression by tapping
Tap the numbers and symbols in order. Used numbers fade, so you can’t use one twice. Undo takes back one step; Clear starts the expression over.
■ Keep your streak going
Each correct answer adds one to your streak and updates your best. Showing the answer resets the streak to 0, so how long you hold out is up to you.
■ Rankings and achievements
Sign in to Game Center to compare your best streak with other players and earn achievements at 5, 10, 25 and 50 in a row. Open it from the trophy at the top right.
■ Your records follow you
Your streak and best are also saved to iCloud. Start on iPhone, continue on iPad, and your best never goes down when devices sync.
■ Nothing extra
• No ads
• No in-app purchases
• No account required
• The app’s only network use is iCloud sync of your records and Game Center
• No personal data collected
A puzzle takes less than a minute. Perfect for a wait at the station or a few minutes before bed.
