## What is Sum Serenity?

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.

MADE TO RELAX

• A big, clear number pad that is easy to tap.
• Pause whenever you need to.
• Music, sound effects and haptics you can switch off.
• No account, no adverts and no internet needed to play.
