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 7-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 7 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.
