How to play

Number Chain practices spotting the rule in a pattern. Each row of numbers follows a rule, and some of its numbers are missing. Tap a loose number, then tap a gap to fill it. Some loose numbers are near misses that do not belong. When every gap is full, press Submit. A hint fills one gap and costs some points. After each puzzle the rule is shown in words.
