Frisian draughts

Frisian draughts is a variant of the draughts family of games native to the province of Friesland in the Netherlands, played on the same ten-by-ten board with twenty pieces per side used in international draughts. Its rules closely follow international draughts, with one notable exception: pieces may capture not only diagonally, as in standard draughts, but also orthogonally, jumping two squares along a row or column in addition to along a diagonal, and any possible multi-jump sequence must be completed once begun. Crowned kings can capture from any distance along an open line, whether diagonal or orthogonal, provided an empty square lies behind the captured piece, giving Frisian draughts a markedly different tactical character from the diagonal-only game it otherwise resembles. The variant remains an actively organized minority tradition centered on Friesland, with its own competitive structure distinguishing it from international draughts and from the other orthogonal-capture variants played elsewhere.
