About 4Sums
What is 4Sums?
4Sums is a collection of daily number-and-word puzzles built on one idea: letters are numbers, and words are sums. Each letter is worth its place in the alphabet (A = 1 … Z = 26). Put +, −, × or ÷ between the four letters of a word and you get a small sum. Each puzzle asks you to find real four-letter words whose sums hit a target exactly.
Target 17 — the word TEAM T=20, E=5, A=1, M=13 20 ÷ 5 + 1 × 13 = 4 + 13 = 17

Getting started
Tap Puzzles and begin with Single, then Reveal and Junction.
Each puzzle opens on a start screen. Tap How to play for that puzzle’s guide, or Tutorial (where available) for a step-by-step walk-through.
The helper tools (the tools button ) give you an alphabet map, a calculator and a word lookup. Switch on Challenge mode on the start screen if you'd rather play without them.
Good to know
Puzzles come in twelve languages: pick one on each puzzle’s start screen. The menus and help are in English.
New daily puzzles arrive at midnight on your device’s clock.
The puzzles are also designed to help with maths and vocabulary, and to introduce real ideas such as ciphers, alphabets and languages, hexadecimal colours, statistics and shapes. The idea first came from primary school children doing sums with letters.
