Minor (and not-so-minor) rule modification has sprouted a number of different variations on Alice Chess.
- Alice Chess 2: the black army starts out on the opposite board (board B).
- Ms. Alice Chess: by John Ishkan (1973). Null or zero moves are permitted. (A move consisting of piece transfer only – from the current square a piece sits on, to the corresponding square, if vacant, on the opposite board.) A king cannot escape check with a zero move, and castling is denied if either king or rook have made a zero move.
- O'Donohue Chess: by Michael O'Donohue (2003). Alice Chess rules, except that a move is permitted even though the square normally transferred to on the opposite board is occupied. (In that case, the transfer portion of the move is omitted.)
- Duo Chess: by Jed Stone (1981). Black starts out on board B; transfers are optional; non-pawn pieces may make zero moves (and may capture in so doing); a king is checked when an opposing piece sits on the king's zero square; mate must cover the king's ability to flee via a zero move.
- Parton also introduced a smaller, 8x4 version of Alice Chess. (See diagram.)
- Parton observed that Alice Chess can be played using three boards instead of two. (Players then having a choice between two boards when transferring pieces.)
Alice Chess rules can be adopted by practically any other chess variant too, by simply doubling the number of gameboards in the variant and applying the piece transfer policy. (For example, Raumschach using two 5×5×5 boards.)

Famous quotes containing the word variations:
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
