The Daily Maritime Challenge is the Binnacle AI Arcade's cross-game competitive feature. Each day at midnight UTC, a new game is selected from the arcade's 32 titles, and a specific seeded scenario is generated for that game. Every player who plays the daily challenge that day competes on exactly the same scenario — the same weather, the same cargo manifest, the same COLREGS situation — making the leaderboard a pure test of skill.
How the daily challenge works
The challenge game rotates across the full library of arcade titles throughout the month, with some games appearing more frequently than others based on their score variance (games with more randomness appear less often to keep the competition fair). The daily game is announced on the arcade's main page and linked directly from the Mariner's Ticket profile.
- Scores are locked to the seed — replaying will not improve your leaderboard position
- The top 100 scores for each day are preserved permanently
- A 7-day streak earns bonus Mariner's Ticket credit
- The daily leaderboard resets at midnight UTC — plan your session time accordingly (for Hawaiʻi, that's 2pm HST)
Competing at the top
Top daily scores typically come from players who have spent time learning the specific game mechanics — not from pure luck. Every game has optimal strategies that become apparent through play. Check each game's How-to-Play guide for tips from the developers.
