How to play STACK

  • • Tap a letter tile, then tap a cell to place it — or just type on your keyboard.
  • • Build the tower from the bottom up: a 3-letter word at the base, growing one letter per floor to a 6-letter word at the top.
  • • Each word must contain every letter of the word below it, plus exactly one new letter. Letters can be rearranged freely.
  • • Use only the 6 letters shown above — across the whole tower.
  • • When a floor is valid, its letters carry up to the next floor automatically; just add the new letter and rearrange to match the clue.
  • • Green = valid containment · Red = a letter is missing or wrong · Solve today's tower to grow your streak and earn XP.
