Four cups, one ball: finding a fair difficulty curve for my iPhone shell game
I’m working on the difficulty curve in Cup Chase, an iPhone shell game that’s already on the App Store.
The basic action is simple: watch the ball get covered, follow that cup through the swaps, and tap your answer. But with four cups, keeping track becomes harder when their paths cross—even before making the shuffle much faster.
This clip shows level 24 at its actual gameplay speed. I want losing a round to feel like something you can learn from, so I’m interested in where the movement becomes hard to read. Would a brief pause between swaps help, or take too much of the challenge away?
If you want to compare this with the opening rounds, it’s free to download and play, with ads and optional in-app purchases:
