4Stack #23 — answers & breakdown
Wednesday, August 5, 2026
Hardware, and a purple group that is conspicuously missing the one device everybody would name first.
The sixteen cards in this puzzle were: Cross, Circle, Square, Triangle, NES Zapper, Power Glove, R.O.B., Rumble Pak, Wii Remote, Kinect, PS Move, Ring-Con, ROG Ally, Legion Go, MSI Claw, GPD Win.
The four stacks
PlayStation face buttons
Cross, Circle, Square, Triangle
The PlayStation face buttons. Sony's Teiyu Goto designed them as concepts rather than letters — the triangle is a viewpoint, the square a sheet of paper.
Nintendo accessories
NES Zapper, Power Glove, R.O.B., Rumble Pak
Nintendo peripherals spanning the NES and N64. R.O.B. existed largely to make the NES look like a toy robot system to American retailers burned by the 1983 crash.
Motion controls
Wii Remote, Kinect, PS Move, Ring-Con
Motion control. Ring-Con is the resistance ring from Ring Fit Adventure and the only one here still in production.
Handheld gaming PCs
ROG Ally, Legion Go, MSI Claw, GPD Win
Windows handhelds chasing the Steam Deck — which is deliberately absent from this board. It is the device everyone reaches for first, and leaving it out is what makes the group take a moment.
