Fifteen: Eras

Fifteen: Eras is a digital version of the timeless sliding puzzle that was popular across the USSR. The game features a 4x4 grid with 15 numbered tiles and one empty space. Your goal is to arrange the tiles in numerical order from 1 to 15, with the empty space in the bottom-right corner.
The game offers four unique visual themes inspired by Soviet aesthetics: Soviet, 80s, Future, and Soft. Each theme gives the game a distinct atmosphere, ranging from retro nostalgia to futuristic vibes.
