Three games worth playing.
From cracking number puzzles to opening a box with no lock to crossing the solar system: three free browser games, each its own small world. No installs, no sign-up to start. Pick a world and play.
Numbers
Numonex
The number-sequence challenge.
Every round hides a secret mathematical rule. Read the sequence, spot the pattern, then predict what comes next, against the clock. Five levels climb from a gentle warm-up to fiendish quadratics and Fibonacci hybrids, so it stays a fair fight whether you last did maths at school or for a living.
Mechanisms
Puzzle Box
Open the box. Then find the box inside it.
A seamless metal cube with no locks and no buttons; only mechanisms waiting to be understood. Turn it, read each face, and find the alignment that wakes it. Solve one box and it transforms into a harder one nested within: sliding brass panels, turning star charts, singing gears, beams of coloured light, and an ancient engine of glyphs.
Cosmos
Solar Explorer
Pilot a ship across the solar system.
Take the helm of the SES Horizon and journey from the Sun to Pluto, visiting all ten destinations and their moons. Real data from NASA and ESA brings each world to life, quizzes test what you pick up, and a tight fuel supply turns every route into a decision. Seventeen badges await the sharpest explorers.
