Checkers Legend is a draughts game that takes the format's regional variations seriously: the settings let you choose which rule set to play, because checkers differs meaningfully between countries — whether kings fly, whether captures are compulsory, whether men can capture backward.
For most people the defaults are the version they grew up with. For anyone who has ever argued about the rules mid-game, being able to set them explicitly is a genuine feature.
It offers settings for the main differences between national versions — most importantly whether kings 'fly' along a diagonal or move one square, and whether captures are compulsory.
A rule in international draughts where a king can move any distance along a diagonal, rather than one square as in English/American checkers. It makes kings far more powerful.
Yes — tap a piece then its square. Nothing to install.
