- Reach
- Only the squares beside you are live. Claiming one doesn't move you, so walk across your own ground, for free, to reach new squares.
- Routes
- Tap a square you can't claim yet to plan a route to it. The route marks each claim with the match you'd make it in: M1 is your next match.
- In the way
- While you can see the Obsession, you can't walk onto or across their square or the squares next to it. An Ambusher out of sight blocks nothing: they find you instead. You can always walk off your own square.
- Sitting out
- If the Obsession cuts you off, or nothing you can reach is playable but something is only blocked, you sit out a match. It's safe: no punishment, and every block drops by one.
- Chases
- If a match ends with the Obsession on your square, a chase starts. Your next match has to hook them, as each Obsession asks, and it isn't counted. Your Obsession is the survivor your perk marks, or with no such perk, one you pick as the trial starts. Fail and they stun you, costing a life. Either way, the Obsession then moves to the square farthest from you, except the Bully.
