How to play
Every game follows the same idea: a few clues, one solution, and logic gets you there without guessing. Here are the rules of each, in a few lines.
Futoshiki
Fill the grid so every row and column has each number once, and every sign holds.
Use the numbers 1 to n once in every row and column. The greater-than and less-than signs between squares must hold: the open side faces the bigger number.
Light UpComing soon
Place lamps so every square is lit and no two lamps see each other.
A lamp lights its row and column until a black wall stops it. Light every white square, never let two lamps shine on each other, and match the number on each wall.
NonogramComing soon
Shade squares from the number clues and a hidden picture appears.
The numbers beside each row and column give the runs of shaded squares, in order. Work out which squares to shade until the picture is complete.
KakuroComing soon
A crossword of numbers: every answer is a sum of different digits.
Fill the white squares with digits 1 to 9. Each run must add up to the clue at its start, and no digit may repeat within a run.
Star BattleComing soon
One star in every row, column and region, and no two stars touching.
Place stars so each row, each column and each outlined region holds exactly one. Stars may not touch, not even at the corners.
SlitherlinkComing soon
Draw one loop around the grid so every number counts its sides.
Connect the dots into a single loop that never crosses itself. Each number tells how many of the four sides around it the loop uses.
