Sonic Zone

Eggman's up to no good again, and only Sonic can stop him! Sonic Zone is a fangame based on the Sonic the Hedgehog series featuring some of the series' characters and very simple controls. Players lead Sonic to the goal while sweeping enemies and avoiding obstacles on the way. Sonic attacks only by jumping on enemies' heads; he doesn't have the ability to roll or use Spin Dash as in the other games of the Sonic series.

Like in the original series, rings are present; players can collect rings for more points. The difference is that the rings cannot keep Sonic alive - touching any enemy can cost Sonic a life. Other items are present: Ring TVs (each adds 10 rings) and Sparkle TVs (make Sonic invincible for a while). Obstacles are not varied: just (mostly) deep pits and spikes. There are a total of 4 zones (Rust Winter, Festival, Riverside and Nocturne), each of which contains 3 levels (two normal levels and a boss level). The boss is always Eggman (running around in the first zone and in his ship in the others). After defeating Eggman in the last zone, the player have to encounter him again in the so-called "Final Act". When the player run out of lives, the game is over and a high score board will be presented. The player will be asked to write their name on the board if their score is at least higher than the lowest score on the board.

The graphics look similar to Sonic CD. There are very few options in the game menu: players only have a choice to play or quit the game.
