${DynamicText("About this genre (loading...)")} §:=paper-puzzle-player.html?W=6&EDIT=1&G=masyu&V= This page gathers the following atomic Masyu Variants (links load a new puzzle in a new tab): - [White pearls optional|§optional-whites|]: visiting each white pearl is optional - [Black pearls optional|§optional-blacks|]: visiting each black pearl is optional - [All black pearls given|§total-black|] - [All white pearls given|§total-white|] - [White pearls inside|§white-inside|]: non-visited white pearls must be inside the loop - [Black pearls outside|§black-outside|]: non-visited black pearls must be outside the loop - [Full|§full|]: all tiles must be visited - [Alternated|§alternate|]: visited pearls must alternate in colour - [Gray pearls|§gray|]: gray pearls that behave as white or as black pearls - [Gray pearls optional|§gray,optional-grays|]: visiting each gray pearl is optional - [Crossing|§crossing|]: lines may cross (even at white circles), but not branch // - [Syuma white pearls|§syuma-whites|]: line must turn on //both// cells immediately after a white pearl // - [Syuma black pearls|§syuma-blacks|]: line //may// turn in exactly one of the cells immediately after a black pearl - [Double|§double|]: there are exactly two loops, one of which must be marked as inverted (black pearls change to white and vice-versa) Atomic variants can be used standalone or [combined|../variants#advanced] into a myriad of variant genres.
