I know this works for after you get the Toad Spell up to 16(might work for before). The boards are on a rotation, find a board that has a solution easy for you to remember.(solve it, and don't worry about how many misses you get this time) Now it will give you the option to start the next game. Say yes, then just give up and move on to the next game. Do this 31 times, then play the 32nd board. It will be the EXACT SAME as the one you solved and memorized!!! Now you can get your time down and get massive amounts of gil and items in no time flat!! I have gotten my time down to 3.85 sec and have stored up at least 80 Masamune blades to sell on top of all the gil I receive for beating it. You can then purposely mismatch a few times to get the other items as needed. Happy Matching!
