Lasker Morris
A variant of Nine Men’s Morris designed by Emanuel Lasker, World Chess Champion from 1894 to 1921. Lasker modified the game to eliminate the sequential two-phase structure: instead of a placement phase followed by a movement phase, each player may on any turn either place a new piece from reserve or move an existing piece already on the board. With 10 pieces per side (one more than standard), the game creates richer interaction as both options remain available throughout most of the game.

| Item | Qty | Notes |
|---|---|---|
| Board | 1 | Three concentric squares joined at midpoints; 24 intersections |
| Pieces | 20 | 10 per player in contrasting colours |
Setup
All 20 pieces begin off the board in each player’s reserve. The board starts empty.
Turns
On each turn, a player must either:
Option A — Place: Place one piece from reserve onto any empty intersection on the board.
Option B — Move: Move one piece already on the board to an adjacent empty intersection (along a connecting line).
Both options are available on every turn until all reserve pieces have been placed. Once a player’s reserve is empty, they can only move existing pieces.
Mill Formation
Completing a mill (three in a row along a board line) on any turn — whether by placing or moving — lets you remove one opponent piece not in a mill. The same mill protection and reopening rules as Nine Men’s Morris apply.
Flying
When a player is reduced to exactly 3 pieces, they may move any piece to any empty intersection (same as Nine Men’s Morris).
Winning
A player wins when the opponent is reduced to 2 pieces or has no legal move.
Strategic Note
The key difference from standard Nine Men’s Morris is that early placements and early movements are interleaved. A player can begin positional movement before all pieces are placed, opening more complex strategic lines.
