The first of three games using a puzzle system somewhere between Minesweeper and Picross. Puzzles are presented on a hex grid with numeric clues that allow the player to deduce which cells must be colored in and which must be blanked out. The clues are a mix of Picross-like ones giving information about the cells in a row or column and Minesweeper-like ones giving information about the cells near another cell, but in both cases there’s some extra variation and complexity mixed in.
