Take the monument.
Walk to a real bridge, windmill or statue. Win one short chess challenge. It turns your colour on every player's map, until someone comes and takes it back.

How it works
Three steps to your first monument
-
1
Find one
Your map shows every monument around you in the colour of whoever holds it. Grey means nobody has claimed it yet.

-
2
Win the challenge
Stand at it and play: thirty to ninety seconds of chess at your own level. A fork, a mate in three, an endgame against Stockfish.

-
3
Hold it
Win, and it turns your colour for everyone and you pocket a pawn. Then somebody from another faction walks up.

Factions
Pick a side
Three factions, one map. Whichever you join, the other two want your street.
Rooks
Straight at it. No detours.
Knights
Always coming round the corner.
Bishops
Halfway across the board already.
Up to four players of one faction hold a monument together. When another faction wins there, all four are out.

The challenge
One challenge. Thirty to ninety seconds.
Opening test
Play the first moves of a named line, as deep as your rating takes you.
Tactic
Fork, skewer, pin. Find it.
Mating pattern
Mate in two, three or four.
Endgame puzzle
One move decides it.
Endgame vs Stockfish
Lucena, Philidor. Convert it, or hold the draw.
Difficulty follows your own rating, so a beginner and a club player both sweat a little. Openings, tactics, mates and endgames are rated separately, because being sharp in the endgame says nothing about your Sicilian.
Free to play
Free, and never pay-to-win
Pawns buy impatience, never strength
Every win earns one pawn, and that is the only way to get one. Saving a challenge to play later from the couch is free. A pawn buys an extra slot, or skips the hour a monument rests after you play it. Nothing you buy wins you a monument.

Free at every monument
Challenging is free, as often as you like. A player on zero pawns is one win away from a full wallet.
Hints cost the win
Take one for free. Solve it with the hint and you keep the answer, not the monument.
Your location stays yours
Read only while the app is open, never in the background. Other players see the monument, never you.
Your map too
Put your club or chess board on the map
Clubs, outdoor boards, and anything the map missed
Does your club play at a fixed venue? Is there a chess table in your park that the map does not know about? Send it in. A person checks it, and it becomes a monument every player in town can walk to. Free, and never worth more in the game than the bridge down the road.
