Chain Math: Six Numbers

Digits: Target Chain is a math puzzle you can play one-handed in minutes — but it will make you think.

Every round gives you six numbers and a target. Combine them with +, −, × and ÷ until you hit the target exactly. The board only lets you play moves that are actually legal, so you can focus on the plan instead of the arithmetic traps.

HOW IT WORKS
• Five tasks per round, one running clock — start, solve, beat your time.
• Pick a number, pick an operator, keep chaining: every step shows the whole expression, so you always see where your calculation is going.
• Operators light up only when they lead somewhere — dead ends stay dark.
• The result of each move becomes the starting point of the next one.

WHY IT STICKS
• Every solved task lands with a satisfying snap of motion and color.
• Your best round time is remembered — a fresh account sets a record on the very first round.
• Rounds are short: perfect for a queue, a commute, or a coffee break.

PURE AND OFFLINE
• No ads. No purchases. No account. Works completely offline.
• The game asks for no device permissions and collects no data.
• Interface available in 26 languages.
