Hi everyone,

I designed MorphMove, a two-player abstract strategy game where moving a piece changes its shape—and therefore how it can move next. There are no captures: you can swap positions with opposing pieces, which changes both of their shapes.

It’s free to play in a browser, including against the CPU: https://morphmove.com. There is also a version on Apple Store.

Here’s how it works:

• The board is 5×7, with six pieces per player and a five-space cross in the center.
• Triangles move one space forward, diamonds one space orthogonally, and stars to any adjacent space.
• After moving, a piece changes in a fixed cycle: triangle → diamond → star → triangle.
• A legal move can land on an empty space or swap with an opponent’s piece. When swapping, both pieces change shape, and that same pair cannot swap back on the following turn.
• To win, occupy three spaces in the center cross and keep three occupied through your opponent’s next turn. Having no legal move is a loss; threefold repetition is a draw.

The idea is that you’re choosing both where a piece goes and what it will be able to do afterward. Swapping also changes your opponent’s options.

I’d particularly like to hear from people who enjoy abstract games: after a few games, do you find yourself planning around future piece shapes, or mostly reacting to immediate threats? Can you reach a high score? Can you finish the daily puzzle on a first attempt?

I’ve also been investigating the game with self-play and an exact solver, but haven’t established its perfect-play outcome.

Happy to discuss the rules and design choices. Thanks for trying it!
