Fill the grid so every row and every column spells a real five-letter word.
Tap a square. Its patch's letter bar jumps to the top, so you can tap a letter to place it.
Each patch's letters go only in that patch, and each one is used once.
No word has a double letter, so the same letter never touches itself side by side or above and below.
A green ✓ only means a finished line is a real word, not that it's the right answer. A red ✗ means it isn't a word. Every puzzle has exactly one solution, so a row of ✓s can still be wrong until the whole grid checks out. Use Check in the ⋯ menu to see which letters are off.
