Mars Rover Game

Pick the landing site. Program the rover. Beat the clock.

Every reload creates a fresh Martian grid. After you choose a safe starting cell, the target rock appears and the planning timer starts. Use F, B, L, and R to complete the mission.

Save the puzzle screenshot, copy the prompt below, then paste both into your chatbot so it returns only an F/B/L/R string.

You are solving a Mars Rover puzzle on an 8×8 grid.

From the screenshot I provide:
- The rover starts on the highlighted landing cell and faces North (toward row 1).
- Brown rock shapes are obstacles. The rover must never move into an obstacle cell; any forward or backward move that would collide with a rock is invalid and ends the mission in failure—plan a route that avoids them entirely.
- The goal is the cell with the orange star marker.

Commands (output as one continuous string, uppercase letters only, no spaces or punctuation):
F = move forward one cell
B = move backward one cell
L = turn left 90° (in place)
R = turn right 90° (in place)

Respond with ONLY the command sequence, for example: FLFRRLB
Do not add explanations, markdown, or any other text.

How to play

Pick any free cell to deploy the rover. The target rock only appears after you choose a landing site.

Plan your route with four commands: F moves forward one cell, B moves backward, and L / R rotate the rover 90° in place.

The planning timer only counts the seconds you spend composing commands before execution starts.

Run the program and watch the rover execute each step. Reach the target rock to win the mission.

Hitting an obstacle or leaving the 8×8 grid fails the run — use New random map for a fresh challenge.
