This game is played on an empty 3x3 square board:

OFF-BOARD - Each player has 8 stones off-board.
DROP PHASE - On the first phase, each player drops a stone into any cell with zero, one or two stones.
MOVE PHASE - When all the stones are dropped, each player on each turn, moves one free stone to an adjacent (orthogonal) cell, if that cell is empty or has a stack with one or two stones.
A stone is free if it is the only one on that cell, or if it is on a top of a stack.
All the stack below the free stone is moved with it.
GOAL - Wins the player that stalemates the adversary.

This game was presented on the old magazine Jeux et Strategie, but it does not mention the game inventor...

An example
