Tic Tac Toe

A simple Tic Tac Toe game written in Leo.

Representing State

Leo allows users to define composite data types with the circuit keyword. The game board is represented by a circuit called Board, which contains three Rows. An alternative representation would be to use an array, however, these are not yet supported in Leo.

Language Features

  • circuit declarations
  • conditional statements
  • early termination. Leo allows users to return from a function early using the return keyword.

Running the Program

Leo provides users with a command line interface for compiling and running Leo programs. Users may either specify input values via the command line or provide an input file in inputs/.

Providing inputs via the command line.

  1. Run
leo run <function_name> <input_1> <input_2> ...

See ./run.sh for an example.

Using an input file.

  1. Modify inputs/tictactoe.in with the desired inputs.
  2. Run
leo run <function_name>

For example,

leo run new
leo run make_move
