Locate a word in the grid of the list. Tap the first and last letter. If the word is on the list, it will be blocked on the grid and removed from the list. Words can be written from right to left, left to right, top to bottom, from bottom to top and diagonally in all directions and can interbreed.
When you have crossed all the words from the list, the definition of the hidden word appears and letters not belonging to any of crossed words are highlighted. Enter the word corresponding to the definition by touching the letters.
