Click the green flag, then either start a fresh round or load a previously saved round. Read the words, think about the answer, then reveal the correct answer and see if you got it right. Words will be displayed again based on the waterfall method (see link in Notes and Credits). To save your progress, click "save piles" and copy the save code. MAKE SURE that to copy the code you triple click and then press ctrl+C. For some reason if you only double click it will not copy the end of the code. The code should end in something like "c1,itrue," or "c3,ifalse," or "c10,itrue," if it was copied correctly. To use this code, click "Load Round From Save" on the start screen and paste in the code. If you would like to remix the project to use a different set of terms and answers, follow the instructions in the "Remix Instructions" sprite.
