Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.
-
Onlie Sudoku — Latin-square uniqueness: sets her lantern on the only place a number can go in its row, column, and box -
Cage KenKen — arithmetic-cage: fills a fenced region so its numbers hit the plaque's target under its operation -
Kaku Kakuro — cross-sum: fills a run so it sums to its clue with no digit repeated; the total names its parts -
Pica Nonogram/Picross — run-length deduction: reads the edge numbers and fills the overlap that must be filled -
Chevron Futoshiki — inequality/ordering: obeys the < / > flags between neighbours to force the numbers into order -
Umbra Hitori — elimination + connectivity: shades out duplicates so none touch and the rest stays whole -
Serra Skyscrapers — visibility count: places towers so each edge clue counts how many can be seen, taller hiding shorter -
Lasso Slitherlink — single-loop edge deduction: draws one closed loop so each number uses exactly that many edges -
Vega Star Battle — partition + non-adjacency: places the stars so each row, column, and region holds its quota and none touch -
Ada Mentor host — keeps the puzzle guild; teaches 'every grid hides one rule — find the forced cell, never guess'
