Multiplication Challenge
Dive with Ollie the octopus through eight reefs, from what × and ÷ mean to every times table up to 12 × 12, in 100 short levels.
What’s waiting inside.
From groups to times tables
100 levels grow from counting shells in equal groups to every fact up to 12 × 12, sharing and division, remainders and two-step stories.
Pictures that show why
Equal groups, arrays, number lines and bar models help every fact make sense before it has to be remembered, and hints show a way to work it out.
Eight reefs to restore
Dive from Shell Shore to Treasure Trench, open a Treasure Chest at the end of each reef, welcome a new Reef Friend and light up the 12 × 12 Pearl Grid.
How to play.
- Tap a reef on the map and choose a level.
- Look at the picture or the question, then tap the answer, or type it on the big number pad in later reefs.
- Finish the level to earn up to three stars, restore each reef and open the next one.
A note for parents
A parental gate, a multiplication question written in words, protects Settings, where parents can turn sound effects, haptics, Reduce Motion and picture helpers on or off and open a progress page for grown-ups. There is no timer on screen and no game over: a wrong answer just means another try, and after two tries a hint shows a way to work it out. Multiplication Challenge works offline, with no account, chat or in-app purchases, and progress is saved on the device. The app shows child-directed, non-personalised ads below the reef map and level lists and sometimes between levels, but never during a level.
