Free during the beta. Works on any phone from the browser, nothing to download from a store.

A quest in play: 1 of 7 steps solved, 100 points, and a compass pointing to the lookout over Marigot, Fort Louis, marked Getting warm at 407 m.
The compass: no map, a needle and a distance.

How it works

We built Quests to turn the island itself into the board. Some riddles you solve from the sofa; others send you out with the compass to find a real spot. Every quest lists its steps, its players and its prize up front, and quests are free to play during the beta.

  1. Pick a quest: a treasure hunt or a quiz.
  2. Read it first: steps, players, prize.
  3. Tap Join the hunt and pick the name you will appear under in the ranking.
  4. Work through the steps, some solved anywhere, some found by compass.
  5. Finish, collect the badge, check the ranking.

The compass

Steps out on the island come without a map. The needle points toward the spot and a label says how close you are, from Far to Getting warm, Very close and You’re here, with the distance underneath. Reach the spot and a find-the-place step counts by itself. Sofa steps are riddles: read the clue, type the answer, and the points are added when it is right.

  • Your location only drives the needle and the distance while the Play tab is open.
  • Without location, the app offers to open the spot in your phone’s own map instead.
  • The free beta quest, First steps on Saint-Martin, has seven steps: four riddles and three real places.

What you can do

  • Quests are free to play during the beta: no entry fee, nothing to unlock partway through.
  • The player count and the prize are visible before you commit.
  • A quest can be a ten-minute break or an afternoon out, depending on its steps.
