These interactive maths games for end of term are eight free browser-based puzzles that bring genuine areas of secondary mathematics to life — from Ramsey theory and topology to logic, permutations and combinatorics.
Each activity is self-contained and runs in any modern browser without a login or download. Use them as a whole-class challenge on an interactive whiteboard, pair students for a competitive session, or let individuals explore at their own pace. Every game includes a built-in mathematical challenge question that connects play to formal reasoning.

Select a game below to play directly in your browser. Each one links to a topic in the KS3 or KS4 curriculum and is suitable for the last lesson of term.
The classic connection game. Drop discs into a 7-column grid and be the first to align four in a row — horizontally, vertically or diagonally. A gateway to combinatorics and game theory at KS3 and KS4.
Claim hexagons on an 11×11 board. Red connects top to bottom; Blue connects left to right. John Nash proved the first player always has a winning strategy — an ideal introduction to topology and graph theory.
Colour the 15 edges of a six-vertex complete graph without forming a triangle in your own colour — or lose. Ramsey’s theorem guarantees a draw is mathematically impossible, so someone must lose every game.
Slide numbered tiles into order on a 4×4 grid — or scale up to 6×6 for an extra challenge. Exactly half of all scrambled starting positions are unsolvable, a fact proved directly from the parity of permutations.
Move three endangered animals and their rangers safely across a river on a two-seat raft. No animal may be left unsupervised with another’s ranger. A rich exercise in constraint-based logical reasoning for KS3.
Start with 32 pegs and one empty hole at the centre of an English cross board. Jump pegs to remove them — the goal is one peg left in the middle. The proof that this is achievable uses group theory and parity invariants.
The Towers of Hanoi is a classic mathematical puzzle where players move a stack of discs between three pegs. Moving one disc at a time without placing larger on smaller, students develop deep recursive logic.
An interactive dots and boxes variant where players draw lines to claim squares. Containing positive and negative integers, it reinforces arithmetic with directed numbers through strategic gameplay.
