Free Space Puzzles

Deep space images make striking jigsaw puzzles: swirling galaxies, colorful nebulas, planets, astronauts, rockets and star-filled night skies. The dense, varied color across a nebula gives you plenty to sort by, while a plain black background scattered with stars can be surprisingly tricky at higher piece counts, since almost every piece looks nearly identical at first glance. Photos of the Moon or a planet's surface add welcome texture and craters that break up the darkness. This free online collection runs from 24 pieces for a quick session to 1,000 for a serious challenge, playable in full screen with no sign-up.
