Unofficial ROM hack. The notes below come from community sources and have not been verified against the patch itself, so levels, mechanics and features may differ from what is described.

Sonic 3 Cz is a fan-made modification of the SEGA Genesis classic Sonic 3 & Knuckles. This isn't an official Sega release; it's a hacked ROM that reworks the original game in various ways. The exact changes depend on the version you find, but the core idea is to alter the experience for returning players. Because it's a community project, information about a specific creator or release date is not widely documented. What you do in Sonic 3 Cz is basically what you know from the original: guide Sonic, Tails, or Knuckles through sprawling side-scrolling levels. You run right, jump on enemies, collect rings, and reach the end of each act. The hack might tweak level layouts, add or remove objects, or change enemy behaviors. Without official patch notes, you'll have to discover the differences yourself by playing. For die-hard Sonic fans who have memorized every loop and spring in the base game, Sonic 3 Cz offers a fresh take on familiar territory. It's not a polished product or a commercial release, but a labor of love that gives you more reasons to revisit Green Hill, Marble Garden, and the rest. If you enjoy exploring alternate builds of classic titles, this one is worth a look. Just don't expect a full conversion or a radically new experience.

How to play Sonic 3 Cz online

Getting Started

When you start a new game, you choose a character - Sonic, Tails, or Knuckles - each with their own abilities. Then you land in the first zone (likely Angel Island Zone if the hack didn't change that). Your goal is straightforward: run to the right, avoid or defeat enemies, collect rings for protection, and reach the giant ring at the end of each act. Rings are your life; if you get hit while carrying rings they scatter, but if you have zero rings and take a hit you lose a life.

The core loop is all about speed and platforming. Memorize enemy patterns and level gimmicks like springs, loops, and spikes. Special stages might appear when you collect enough rings. Since this is a hack, some mechanics might be altered - for example, the way shields work or the placement of checkpoints. Take your time exploring each act to notice what changed from the original.

There are no menus to navigate once you start - everything is real-time. If the hack changes the level order or adds new acts, you'll discover that naturally as you play. The best approach is to treat it like a new version of a game you already know: experiment, expect surprises, and don't be afraid to lose a few lives figuring out what's different.
