Their mistakes are your map
How to play Trapdoor Panic with a friend
- Start at the bottomBoth players begin on the same tile at the bottom-centre of a seven-row, five-column grid.
- Step on your turnPick an adjacent tile and commit. You find out what it was only after you've stepped.
- Solid or trapdoorA solid tile advances you. A trapdoor drops you all the way back to the start.
- Read the revealed mapEvery tile either player uncovers stays marked for both of you. Their fall tells you where not to go.
- Reach the topFirst player to cross the grid wins.
Going first is a real cost
Whoever is further ahead is stepping on unrevealed tiles, and unrevealed tiles are where the trapdoors are. The player behind walks a route that's already been proved safe.
That produces a genuine rubber band. A big lead means you're doing all the exploring while your opponent strolls up behind you on your own verified path — and one bad tile sends you to the bottom while they keep the map you drew.
Being slightly behind is often the strongest position on the board, which is not something most racing games can say.
Falling back to the start isn't as bad as it looks
A trapdoor sends you all the way down, which feels catastrophic and usually isn't — because the route you already verified is still verified. You walk back up the known-safe path quickly and resume at the frontier.
What you actually lose is turns, not knowledge. The knowledge is permanent and, annoyingly, it's your opponent's too.
Three things that actually help
- Don't race to the front early. The leader pays for every discovery and the chaser gets it free.
- When you're ahead and the frontier is wide, prefer a tile next to one you've already proved. Trapdoors cluster less painfully when your fallback route is short.
- Remember that your falls help them. If you're already behind, that's fine; if you're ahead, every risk you take is a gift.
Trapdoor Panic questions
Do both players see the same trapdoors?+
The layout is hidden from both, but once a tile has been stepped on it stays revealed for both players. Whoever discovers a trapdoor pays for it; everyone gets to see it.
What happens when I hit a trapdoor?+
You go back to the starting tile at the bottom of the grid. You keep every tile you'd revealed, so the walk back up the proven route is quick — you lose turns, not information.
How big is the grid?+
Seven rows by five columns, with both players starting on the same bottom-centre tile.
