Recall the two pegs, then tap the number.
Forward drill
Number → word grid
Start from the number, flip to reveal the word and image. This is the encoding direction for placing facts.
Reverse drill
Word → number grid
Start from the word, flip back to the number. This closes the loop so the deck works as both index and recall test.
