How do you play Orbit Forecast?

Start a 70-second run, then for each of the 3 checkpoints select the card and tap one of the 12 outer sectors to predict where that satellite will be on the listed beat. Press Launch Forecast and the game checks each prediction automatically as the satellites move.

What makes Orbit Forecast tricky?

It is a prediction puzzle, not a reflex game — the satellites travel at different signed speeds, so you have to mentally simulate their future positions before you launch. Sectors also wrap around the ring, which makes fast mental math the real challenge.

How does a run end and how is score counted?

Clearing all 3 checkpoints in a round advances you and adds one to your clear count. A single wrong sector or running out of time ends the run, and your score is the number of rounds you cleared.

Why did my satellite end up in a different sector than I expected?

Each satellite moves by its velocity every beat, and negative velocities run counter-clockwise while positions wrap past sector 12 back to 1. If your prediction was close but off, you likely missed the wrap-around or used the wrong sign.

Is Orbit Forecast free to play?

Yes. Orbit Forecast is completely free to play in your browser with no install and no signup. Your best clear count is saved on your device, and strong runs can be submitted to the global leaderboard.

HOW TO PLAY

Press Start Forecast to begin a 70-second run.
Each round shows 3 checkpoints. Select a checkpoint card, then tap one of the 12 outer sectors to predict where that satellite will be when the listed beat arrives.
Launch Forecast starts the simulation. At each checkpoint beat, the game automatically checks the predicted sector.
Clear all 3 checkpoints to advance. One miss or running out of time ends the run.

TIPS & STRATEGY

Read each satellite's signed velocity from the legend before placing a marker — a +2 satellite jumps two sectors per beat clockwise, while a -1 drifts one sector back, so just multiply the velocity by the checkpoint beat and add it to the start sector.
Sectors wrap around all 12 slots, so when your math runs past sector 12 keep counting from 1 again — most early misses are off-by-twelve wrap mistakes, not bad reads.
Lock in the checkpoint you are most certain about first, then use the auto-advance to the next empty card to keep a steady planning rhythm before time drains.
Double-check every marker before pressing Launch Forecast: one wrong sector ends the entire run, so spending a few extra seconds verifying beats rushing all three.

ABOUT

Orbit Forecast is a prediction puzzle, not a reflex game. The satellites move at different signed speeds, so the challenge is mentally simulating short future states before you press launch. That makes it feel different from direct-control arcade games: the key skill is forecasting motion on a single screen. Your best clear count is saved on your device, and strong runs can be submitted to the global TOP 20 leaderboard.
