Number Reef: Swim & Learn

Learn math while exploring a colourful underwater world.

You are the fish. Swim through the ocean, solve each question, and catch the bubble with the correct answer. Avoid incorrect bubbles, protect your lives, build winning streaks, and collect points to unlock new characters.

LEARN WHILE YOU PLAY

Choose what you want to practise:

• addition
• subtraction
• multiplication
• division
• percentages
• mixed questions

Select the type of questions that suits you and improve your maths skills through play.

CATCH THE CORRECT BUBBLE

Each question appears with several answer bubbles. Swim towards the correct answer and avoid the wrong ones.

Choose carefully. A wrong bubble costs you a life, so stay focused and react quickly.

BUILD A STREAK

Answer five questions correctly in a row to activate a streak and earn double points.

Keep choosing the right answers to maintain your momentum, improve your score, and unlock rewards faster.

WATCH FOR HELPER FISH

Special helper fish sometimes swim across the screen carrying useful bonuses, including:

• point multipliers
• extra lives
• other helpful power-ups

They swim fast, so stay alert and catch them before they disappear.

UNLOCK NEW CHARACTERS

Collect points while you play and use them to unlock new fish characters.

Keep practising, improve your high score, and expand your underwater collection.

PRACTISE AT YOUR OWN LEVEL

Choose the calculations you want to practise and play at a level that matches your ability.

Start with simple sums or challenge yourself with multiplication, division, percentages, and mixed questions.
