Privacy-friendly and ad-free educational games from an independent developer in the UK.

For family

Dungeons & Digraphs

For children in Reception to Year 6 (ages 4–11), and their parents

A fantasy spelling adventure built around the National Curriculum spelling lists, with a switch for US spellings. Children create a hero, go on quests and defeat monsters by spelling words, and the words they miss come back until they stick. Grown-ups can type in this week’s list from school and follow progress. Free to play, with no ads, no accounts and no tracking.

Maths & Martians

For children in Reception to Year 6 (ages 4–11), and their parents

A space maths game where cadets defend their Mars colony from cartoon aliens by solving sums. It covers number facts, times tables (with practice for the Year 4 Multiplication Tables Check), money, fractions and telling the time, following the UK National Curriculum, with options for the US, Canada and Australia. Free to play, with no ads, no accounts and no tracking.

For business

Breach Inc.

For security, tech and business leaders

An interactive data breach simulation, written by someone who’s been there. You’ve just joined the senior team when a major breach lands, and every call you make costs time, influence and the health of your people. Play it in your browser, then take the lessons back to your own team. Free, and organisations may use it in their own internal awareness programmes.
