cliard24 is a command-line 24-point card game. It provides two main functions: the game mode allows you to play the classic 24-point game interactively in the terminal, where you randomly draw 4 cards and use addition, subtraction, multiplication, division, and parentheses to reach 24; the solve mode lets you input any combination of numbers and a target value to calculate all possible expression solutions. The tool supports customizable attempt limits, endless mode, solution count limits, and mixed input of card letters (A/J/Q/K) and numbers.
