Hard Jigblock uses a 5x5 board, which means more detail, more planning, and more value from every locked section you build.

5x5 picture block puzzle
Basic rules
Swap any two tiles
Every move exchanges two tiles, so planning matters more as the board becomes denser.
Use locked groups well
Correct sections merge automatically, and those stable groups become the foundation for the rest of the solve.
Rebuild the whole image
Hard keeps the same goal as every other board, but asks for more patience and cleaner decisions.
About hard Jigblock
Hard Jigblock serves players who want a longer picture puzzle session without changing the core rules. The 5x5 grid makes color matching, local detail, and endgame cleanup more important.
If you need a quick reset, review the rules or step back to medium before returning to hard.
