Each day brings five targets. For each one you get six numbers. Tap a number, an operation (+, −, ×, ÷), then another number: the two combine into a new number. Keep combining until you hit the target exactly. You don't have to use every number. Only whole, positive results are allowed.
Hit a target exactly for three blossoms. Within 10 earns two, within 25 earns one. The best daily score is 15. Share your result without spoilers, keep your streak going, and play unlimited practice puzzles any time.
Sumbloom is a free arithmetic puzzle in the spirit of classic "numbers round" games. Every player in the world gets the same puzzle on the same day, and every target is guaranteed solvable. It works on phones, tablets and desktops, offline too once loaded, with no account and no ads.
Yes. Free: every daily puzzle, the archive and unlimited practice puzzles, with no ads, no account and no limits.
Only whole, positive results are allowed, the same rule as the classic numbers round. It keeps every target solvable and every step easy to check.
It highlights the next move of a real solution. A target solved with a hint is worth at most 2 blossoms, so the 3-blossom score stays honest.
