Knucklebones
The viral dice-grid duel (popularised by *Cult of the Lamb*), you versus a greedy CPU. You each own a **3×3 grid of three columns**. On your turn you roll a die and drop it into one of your columns. The hook: matching dice in the **same column multiply** — two 4s score 4×2×2 = 16, three score 4×3×3 = 36 — and dropping a value **destroys every matching die in the opponent's same column**. When either grid fills, the game ends and the higher total wins. Equal parts greed, stacking, and sabotage.
Knock Stack
An evergreen throw-to-topple physics template: drag back to launch a ball and knock every block out of the stack before the balls run out.
Knight's Tour
The centuries-old chess puzzle. A lone knight starts on the board; hop it in its L-shaped moves and land on **every square exactly once** to complete the tour. Green dots show your legal moves, a glowing trail numbers the path you've walked, and you can undo any time you paint yourself into a corner. Boards grow from a gentle 5×5 up to the classic 8×8.
