10月7日的Three Tells应用程序分析

A safe you crack by feel. Turn the dial slowly and the taps under your finger change their rhythm. There are three tells: a tap, a double tap, and a silence. Somewhere in the rhythm is a pattern. The plate on each safe tells you how to read it. Find the number, set it, and feel the wheel seat. Three wheels open the safe. There is no clock. Turning slowly is the whole skill: hurry, and the pattern disappears. Five short training safes teach you the three tells. After that every safe is new, nobody has cracked it before and nobody will crack it again. Cracked safes go in your notebook. Nothing to buy, nothing to unlock, no ads, no account. Nothing leaves your phone. Three Tells is played through the iPhone's haptics, so it needs an iPhone that can tap back, and a slow hand.
