Drag one continuous worldline through a field of cosmic objects — particle, asteroid, moon, planet, star, neutron star — consuming them in ascending order of mass while filling every cell of spacetime. Reach the black hole last and the whole region collapses to a point… then blooms into something larger. Singularity: Collapse is a minimalist one-line puzzle with a cosmic soul. Easy to learn, deep to master. HOW TO PLAY • Trace a single unbroken line with your finger. • Swallow each object in order of its mass. • Fill every cell, then collapse into the black hole to win. FOUR WAYS TO PLAY • TODAY'S WORLDLINE — a daily puzzle, the same board for everyone worldwide. Build a streak, earn badges, and share how you did. • ENTROPY — endless high-score survival. The longer you last, the more the universe destabilizes; solving vents the entropy, but fill the bar and it's heat death. Easy, Medium, Hard. • DECAY — survival's precise mirror, with no clock. The black hole evaporates through Hawking radiation — every reversal shrinks it, every flawless solve rebuilds it. Hold it together as long as you can. • SYNTROPY — your sandbox: pick which mechanics appear and play at your own pace, timed or relaxed. AN UNFOLDING UNIVERSE As you climb, new rules reveal themselves — wormhole pairs, mass gates, gravity wells, an entangled pair caught in superposition, and stacked multiverse boards woven together by bridges. Each one is taught the moment you meet it. MADE TO PLAY ANYWHERE • Play offline — every puzzle is generated on your device. No account, no sign-up; your progress stays on your phone. • A soundtrack of synthesized public-domain classics: Bach, Satie, Chopin, Tchaikovsky… and a surprise or two. • Achievements, streaks, and a Field Guide that fills in as you explore. • A clean, minimalist cosmic look, with an unlockable Penrose spacetime skin.
