Four paper monster friends hold up the answers. Tap the right one to push the meteor back.

Kidi Monster Math is a calm, colourful maths game for children learning addition, subtraction, multiplication and division. Every monster, planet and button is cut from paper, each monster has its own voice, and a wrong answer is never a dead end: the right answer glows, its monster cheers, and the next sum comes.

WHAT YOUR CHILD CAN DO\
• Plus Minus: addition and subtraction that grow harder level by level.\
• Multiply Divide: multiplication and division that grow harder level by level.\
• Times Tables: practise any table from 2 to 10, with division and the missing factor in later levels.\
• Daily Challenge: the same ten sums for everyone each day, a stopwatch and a streak to keep.\
• Choose the pace: Fast (the meteor at full speed), Relaxed (it creeps, and every sum is read aloud) or No timer (no meteor, no pressure).\
• Help when a sum is hard: counting dots under small numbers, a speaker that reads the sum aloud, and wrong answers that are near misses, so every choice makes a child think.\
• Rewards that add up: stars for each stage and table, stickers, and eight hats to dress the monsters in the wardrobe.\
• Five right in a row earns a bonus point and knocks the meteor back.\
• Plays in portrait and landscape, on phones and tablets.

FREE, WITH NO ADS\
Plus Minus, Multiply Divide, every times table from 2 to 10, the Daily Challenge, all three timer choices, every learning aid, stickers and hats, and the parents' settings are free. There are no ads and no subscription.

KIDI MONSTER MATH PRO\
One optional in-app purchase, made once, unlocks:\
• Mix Mix, the hardest stage: all four operations, and the "?" can hide anywhere in the sum, even in place of the sign.\
• Practice: a calm round built from the sums your child misses most. When they get one right, it drops down the list.\
• Parents' reports: right answers for each operation, time played, the sums missed most, and a week-by-week history.

BUILT FOR CHILDREN, SET UP FOR PARENTS\
The parents' corner sits behind a 4-digit PIN. Prices, buying and restoring a purchase appear only there. If a child taps something locked, they simply hear "ask a parent". They never see a price.

The game is in English, with the sums and the monsters' names read aloud. It suits children from about 5 to 10: early counters can play Plus Minus on No timer with counting dots, and older children can race the meteor through the times tables.

Plusk, Mynus, Divy and Mully are ready. Can your child keep the earth safe?
