Dr. Robotnik's Mean Bean Machine is an 'Adventures of Sonic the Hedgehog'-themed reskin of Japanese falling block puzzle game Puyo Puyo and it's a heck of a good time.

The premise of Mean Bean is simple but addictive. Pairs of beans fall from the top of the screen and you have to join them together in batches of four or more to pop them off your board. When you do, it makes a rock appear on your opponents board so by clearing your own board you're simultaneously disrupting your opponents. Crucially, you can build your board up patiently and then get rid of an epic amount of beans in a chain combo, which in turn, creates an avalanche of rocks on your opponents board.

This is the central risk reward matrix at the heart of Mean Bean's gameplay and adds a delectable layer of tension. Do you build up a monstrous combo and leave yourself vulnerable to enemy rocks or do you try to overwhelm your opponent with a continual string of smaller combos?

It's a formula that's easy to grasp but takes time to master and the single-player mode does a good job of testing out your skills. I always found Mean Bean's single-player mode hit a sweet-spot with it's difficulty curve. Every robotic opponent has a distinct playstyle but they get progressively tougher to beat, pushing you to continually blast through your own perceived skill ceiling in an effort to get further. It's the type of game I find endlessly replayable and satisfying to best.

For what it's worth, I enjoy Mean Bean over the original Puyo Puyo because of it's AOSTH inspiration. It's so much fun to see the goofy enemy portraits change from smug grins to desperate, sweating faces when you turn the tide in your favour. The tense Kraftwerk-inspired music and excellent use of well-placed sound effects (an exuberant YIPEE sounds off whenever you pop a quad of beans) only add to the satisfaction when you've got Dr. Robotnik or one of his lackeys on the ropes.
