See all 404Where to use it
Toy shops and kids brands can turn their error page into a classic sliding puzzle. Eight lacquered tiles sit in a wooden tray, shuffled on load, and together they form a big white 404 on a red, yellow and teal gradient. Each tile shows its own slice of the image, so it reads as one picture once solved.
Click a tile next to the gap or use the arrow keys to slide pieces. A status line confirms the solution, and the shuffle button starts again. Change the teal accent for the solved glow and the button.
