Hexathlon

A skill gym for the micro-skills of hex-board trading games: reading pips fast, trading efficiently at ports, and tracking a rival's hand. Short timed formats, a 5-puzzle Daily, 13-puzzle Rush runs and friend challenges. Mobile-first, no AI at runtime.

• Pip Flash: tap the corner touching the most pips before the clock runs out.
• Port Math: see the hand, the build and the trade rates; tap the fewest trades it takes.
• Hand Tracker: follow a game log, then count your rival's cards.

Modes: Daily (5 puzzles per format per UTC day, the same for everyone, one scored attempt), Rush (13 puzzles, easy to hard), Pip Flash quick sets of 3, 5 or 10, and challenge links so friends play the same 13 puzzles. A streak ("days at sea") counts consecutive days with a Daily, and a relaxed mode doubles every time limit.

Everything is generated from an integer seed, so the same seed gives an identical board and puzzle on every device.
