This one's dangerous. In a good way.
You tap cards that are one higher or lower than your base card. That's it. 5, then 6, then 7, then 6 again. Back and forth. Chain as many as you can. The longer the streak, the bigger the points.
And those streaks? Addictive. You get into this flow state where your finger just knows where to tap next. Tap tap tap. Cards flying off the peaks. Brain completely empty. Pure muscle memory.
The three mountains slowly flatten as you clear them. There's something weirdly zen about it. Like those videos of people pressure-washing driveways. Just... satisfying destruction.
Perfect for: waiting for food delivery. Avoiding eye contact on public transit. That 15-minute window before a meeting when you can't start anything real.
Warning: "one more game" is a lie. You'll play twelve.
