Daily Maritime Challenge — Compete Globally

Every day a new maritime challenge is posted. Every player in the world plays the same seeded scenario. Your score goes on the global leaderboard at midnight UTC.

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.

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.

Frequently asked questions

When does the daily challenge reset?
The daily challenge resets at midnight UTC. For players in Hawaii (HST = UTC-10), that's 2:00 PM local time.
Can I play the daily challenge more than once?
You can play the game multiple times, but only your first qualifying run on the seeded daily scenario counts for the leaderboard.
What is a Skipper streak?
A streak is the number of consecutive days you've completed at least one game session. A 7-day streak earns bonus Mariner's Ticket progress. Streaks reset if you miss a day.
How are ties broken on the leaderboard?
In the event of a tied score, the earlier submission ranks higher. Leaderboards also show each player's handle, which you can customize in the arcade settings.
