• Defeat some/all enemies and/or collect all rings
  
• Defeat a boss
• Find the exit
• Get the Time Stone (in special stage levels)

    In order to clear levels, the player will have to move between the past, present, and future time zones by time travel. Like in the original game, time travel is done by hitting a past or future sign, and then waiting ten seconds. Time travel can be cancelled by moving the pad over the "Time Cancel" brick on the bottom right corner of each level. A timer for the time travel is shown, and a sign icon shows the relative time going to (past/future). The current time zone is indicted by Sonic's life icon (either a Sonic head for present, "P" for past, or "F" for future), and by the level's background, border, and level art, which will change accordingly to the time zone. Due to sound slot space limitations in the original Break GOLD engine (only 100 sfx), all zones use the US present mix of the zone's music, "streamed" in 14.20s wave file chunks. By going into the past time zone, and by destroying the electric cage, Sonic can create a "Good Future" time zone; otherwise, by not hitting the cages, Sonic will have a "bad future" time zone. Boss levels only have a good/bad future time zone. Also similarly to the original Sonic CD, rings, which you can collect throughout the levels, act as health. Hitting painful objects, such as spikes and some enemies, will reduce 5 to 10 rings per hit, while some objects insta-kill Sonic. Hitting an object with a shield powerup or while being invincible will prevent getting hit for one collision. Getting hit with zero rings decrements a life. Gathering 100 rings rolls back the counter down to 0, and gives the player an extra life. The game also contains the Break GOLD engine's original powerups, as well as Sonic monitor powerups, too. The original, built-in powerup bricks may fall upon being hit, and letting them collide with the paddle awards the powerup.

Built-in Powerups:

Brick Image	Brick Name	Description
	Multiball	Creates multiple Sonic clone balls
	Penetrating ball	Makes primary Sonic ball yellow/super, allows him to bust through some bricks without rebound, and ghost through semi-transparent blocks
	Enlarge brick	Makes the paddle larger
	Shrink Brick	Makes the paddle smaller
	Random brick	Can be any of the above bricks. Often generates silver rings, which, when collected with the paddle, earns points

Monitor Powerups:

Monitor Image	Powerup name	Description
	Ring	Gives the player 10 rings
	1up	Gives the player an extra life
	Shield	Allows the player to be hit once without losing rings
	Invincibility	Allows player to avoid getting damage and can destroy spikes on collision
	Speed shoes	Instantly sends player to the next time zone
	Slow shoes	Instantly sends player to the previous time zone
	Special stage monitor	Allows player to access the special stage for the Round (after the boss)
	Ball Saver	Enables the ball saver at bottom of screen. Ball saver has 3 hits, and changes from red springs, to yellow springs, to spikes before disappearing
	Clockstopper	Freezes all ring and enemy movement for a limited amount of time
	Warp	Kills and then gives a 1up, in order to "warp" player back to paddle

    Furthermore, the game consists of special stages, which are a combination of Sonic 1 (similar brick graphics, but no level rotation), Knuckles' Chaotix Bonus Stages (psuedo-3D layers), and Sonic CD's scrapped Bonus Stage concept. These special stages are for Act 4 for each Round, and can only be accessed if the player hit a Special Stage monitor in the Round. The player's goal is to traverse between the multiple level layers in order to get the Time Stone. The player can see up to 3 layers forward from the current layer, since further layers are semi-transparent and are shown smaller. Traversing the layers is done by hitting up/down arrow bricks. Getting all of the time stones will allow the player (in the finished build of the game), to goto Final Fever Zone and to defeat Dr. Robotnik for the final time! In the special stages, the player is given 4 special stage lives and given 90 rings. These rings will decrement to zero, in which a special stage life will be deducted. If all 4 special stages lives are lost, the player is kicked out of the special stage, fails, and can't get the Time Stone! The zone consists of solid bricks, breakable bricks, bumpers, spike balls, and an elevator platform. This platform follows the x-coordinate of the main paddle, and its y coordinate can be altered by letting the paddle collide with up/down bricks. Some levels also contain spikeballs, which, upon being collided with, cause Sonic to lose 5 rings. There is also 1 Big UFO object in each level, which, after being destroyed, gives the player 75 rings. Each special stage also has a slot machine, which can be played by hitting the slot bricks. The following rewards can be earned if each slot has 3 of the same:

Slot image	Image Name	Award
	Sonic	Awards 75 rings
