How to unlock the Past a Heap of Puzzles achievement in Catherine - Definitive Guide
Or if you want wait till you beat the game and you get infinite coins during your second playthrough, which was mentioned by TOO Taco Bob
Once you saved play rapunzel until you have no more credits, it will save your progress after each level, so the level you are at can always be continued. Once you can't play anymore leave the machine and quit out to the menu screen then go back to the save before you clicked on the arcade machine.
You should be able to continue your progress with the same amount of coins too.
Just keep doing this until level 64.
And if you need any help with any levels, here is a playlist of videos on how to do each level from 1 - 64 in Rapunzel if you get stuck. Thanks to XCVii007r1 on youtube.

This achievement is obtained through the arcade game Rapunzel, playable in the Stray Sheep during the day. It will unlock once you have beaten the first 64 stages of the game; full maps, videos and strategies can be found HERE. Each night you are allowed three plays, but once you finish the game, 'Free Play' is unlocked, where you have unlimited plays.
Rapunzel is the arcade game available to play at the Stray Sheep Bar. It is a retro-classic version of the actual gameplay in the Catherine Nightmare Stages in Golden Playhouse. There are a total of 128 levels, with 64 levels in each mode. During your initial playthrough you only get to get 3 credits per day. Once you complete the Golden Playhouse in subsequent playthroughs, Free Play mode becomes available with unlimited credits. For this trophy, you just need to clear and beat the initial 64 stages.
XCVii007r1's channel has a video solution to each of the Rapunzel 128 (each 64) stages for the highest scores.
