After a game has finished, a list of the five words from that game and their readings and meanings are shown.
The score is shown above, compared to the high score
The current completion status of the words are shown as colored stars. N.B. These stars' colors can be manually adjusted simply by tapping them to cycle through the colors. This is so you can either check words off (ie rate them green) if you don't feel a need to have that word appear in further games, or rate them lower if you feel you actually need more practice with a particular word.
Any kanji in any word can be tapped on to jump to a flashcard showing meanings, readings and compounds for that kanji. (*addendum - temporarily this function is limited to kanji in the same level.)
