You Win!

Pretty simple state explosion. We need to know which letters we've typed from our final word, the current value of the spinner, and the current cursor location. That's 2^20*26*20 = 500 million

Then for each action, we can move, or spin the spinner or type the letter under the cursor, which is 5 constant time operations. Borderline, but should run fast enough with lax midatl timeouts.
