FREQUENTLY ASKED QUESTIONS

Yes. LOST is played in the physical world. You walk, run, strategize, and physically locate your target using GPS. Eliminations happen through your phone's AR camera when you're close enough. This is not a sit-on-the-couch game.
There are no props and no physical contact. An elimination is confirmed on your phone, in AR, only when you're within 20m. Schools, hospitals, places of worship, and every player's home base are safe zones where nobody can be eliminated. Elimination is disabled above 25 mph, so nobody plays from a car.
Four. Any player can create a free tournament, set the format and play area, and share the join link or code. Tournaments start within a week of being created and run until one player is left.
Yes. All tournaments are free to enter. You compete for points and leaderboard rankings. Free tournaments are ad-supported.
Every player is assigned exactly one target and is being tracked by exactly one other player, forming a circular chain. When you eliminate your target, you take over their target. The chain shrinks with every elimination until only one player remains.
Certain locations, like schools, hospitals, places of worship, and your personal home base, are designated as safe zones. You cannot be eliminated inside a safe zone, but your health meter will deplete while you're there. You can't hide forever.
Your health depletes when you're offline, in a safe zone, or outside the play area. It recharges when you're actively playing in bounds. If your health hits zero, you're automatically eliminated. It keeps the game moving and rewards active players.
You must be at least 13 years old to play LOST.
LOST is available nationwide in the United States, free on iOS and Android.
