Starseek

Four spaceships are hidden in today's galaxy, and every player in the world gets the same one. Each scan you fire reports how many ships lie on the eight lines through that point — a zero clears eight whole lines at once. Find all four in as few scans as you can, then share a spoiler-free grid and see your rank among the day's solvers. Streaks, achievements, an all-time leaderboard ranked by average scans, plus turn-based duels and live two-player races for when you'd rather beat a friend than the clock. Free, no signup, no ads. Runs in any browser, made for phones. A homage to Galaxis (1980) — with the beeps.
