Play Denki Blocks (J)(Chakky) Online

Denki Blocks! is one of those weird little GBA puzzle games that somehow sticks with you. You're dropped on this island full of block-pushing puzzles, each with its own quirky "mastermind" character who acts like they invented the concept of moving squares around. The first few puzzles ease you in—just slide blocks to match colors—but then they start throwing in weird mechanics like teleporters and blocks that only move when you're not looking at them.

What I love is how the game doesn't take itself seriously. The masters you challenge all have these ridiculous personalities, like the guy who's way too proud of his "unstoppable" puzzle that you solve in three moves. And the music? Weirdly catchy chiptune stuff that gets stuck in your head while you're trying to figure out why your solution isn't working.

It's the kind of game where you'll get stuck on one puzzle for 20 minutes, walk away frustrated, then suddenly sit up in bed at 2 AM realizing the solution was stupidly simple. If you like Picross or Sokoban but wish they had more personality, this one's a hidden gem.
