Mendel Palace

Mendel Palace is an unusual NES action-puzzle game from Game Freak, published by Hudson Soft in 1990. Rather than relying on jumping or weapon attacks, it builds its challenge around a grid of reversible floor tiles. Each stage is a compact arena filled with enemies, and the player must turn tiles over while moving through the layout, using the changing floor to disrupt and defeat the creatures.

The controls are easy to understand, but the situations become increasingly demanding. Enemies patrol the board and can trap the player if movement is careless, so success depends on reading their positions, choosing a safe route, and flipping tiles at the right moment. Turning over a row can send nearby enemies away, making the central mechanic useful both offensively and defensively. At the same time, limited space and constantly shifting enemy positions give every room a tense, quick-thinking rhythm.

Mendel Palace has a colorful, offbeat presentation that reflects its arcade-style design, while its simple rules leave plenty of room for experimentation. It is the sort of game that can look straightforward at first, then reveal a surprising amount of strategy once later stages demand more precise timing and positioning. The two-player option adds another way to enjoy its maze-like arenas, whether competing for better performance or sharing the challenge.

For NES players, Mendel Palace stands out as an inventive early title from the studio that would later become famous for Pokémon. Its blend of action, spatial planning, and playful tile-flipping remains distinctive among the console’s puzzle games.
