Now that I'm back home and rested from WSPC and setting puzzles for GAPP again, I can finally pick some genres from all the new sources that became available in the past month or so. First up is a new omopa genre from Nikoli's most recent Puzzle Communication!
Also, if you'd like to read about my WSPC experience or take a stab at the practice puzzles I wrote for the event (note these are not necessarily GAPP level), have a look at my recap here!
Today's GAPP is a Tetrochain-K, the latest addition to the Tetrochain family!
Rules: Shade some tetrominoes of cells such that no two tetrominoes touch each other orthogonally, but all tetrominoes form one diagonally connected network. Two tetrominoes of the same shape may not touch diagonally, counting rotations and reflections as the same. Black circles indicate there are more shaded than unshaded cells among the cells the circle overlaps. White circles indicate more unshaded cells, grey circles indicate the amount of shaded and unshaded cells is equal.
Try recent Tetrochains here (note that these puzzles have slightly different rulesets!):
