Sum Serenity is a calm mental maths game. Solve quick sums against a gentle clock as you wander a winding path through five peaceful, illustrated worlds, with soft music to keep you company. FIVE WORLDS, 75 LEVELS • Lily Pond: warm up with addition. • Mossy Forest: subtraction joins in. • Signpost Village: multiplication, starting with the times tables. • Butterfly Garden: division joins the mix. • Candlelit Festival: the toughest sums of all. Each world builds slowly, so the sums grow with you and never feel out of reach. THREE STARS TO CHASE Finish a level with time to spare to earn up to three stars. Replay any level to beat your time and fill in the gaps. SECRET LEVELS Earn every star in a world to open its secret level: a longer, quicker run along a moonlit path. ENDLESS MODE Pick your sums and your pace, then see how far you can go. Every right answer wins a little time back, and your best run is saved.
