Games / TriQuad Remake
« Last post by B+ on July 21, 2019, 01:51:05 AM »This is total overhaul of Rick's TriQuad clone done in Naalaa some time ago. This game allows user to choose from 3 to 9 square pieces per side, uses a different method to build the puzzle and uses a different method to detect/check solutions since it is possible by random luck to have multiple solutions to a puzzle.

) and I tend to divide my practice (playing?) time between different BASICs and other languages.
