The Introductory Stage (aka Basic , Checkpoint 0, or Start) is the first checkpoint that appears in Classic, Training, Mayhem. It acts as the game's tutorial. This checkpoint has been in all public versions of the game.
The introductory stage is mainly white, with grey glass. The gradient is mainly white, while in the previous segment a green tint is added. While in this zone, you are known as a beginner.
This area contains three segments, and once completed the player enters Checkpoint 1.
Since it is the first checkpoint in the game, the introductory stage is very easy compared to other checkpoints appearing later on. The glassobstacles here pose little difficulty, except for a few, tricky Sliding Glass Panes.
Introduced features
This checkpoint introduces the basic mechanics of the game. During the first segment, notifications will appear to inform the player about firing balls, crystals, and Multiball. A notification also appears if the player crashes into an obstacle.
In the Introductory stage the player will first encounter crystals in their basic form; pyramid-shaped. The first glass obstacles are also found here, although only two types are introduced. Long glass bars are situated at various places, and sliding glass walls are common.
The main area consists of many pyramid crystals placed in groups. Just before the exit, the player runs into a glass bar, the first obstacle encountered in the game. After this is the exit door, as well as two pyramids placed alongside it.
This segment is slightly more challenging than the previous, as more obstacles are found. New sliding glass panes are encountered, which slowly move in a horizontal direction, as well the glass bars seen earlier. Crystals are often placed in more hard-to-reach locations, and some are placed atop vertically-moving columns. The end door is accompanied by two crystals placed in a similar matter as the previous segment, with one button needed to open it.
3 (Darker)
This segment only contains the obstacles found in the previous segments, as well as crystals placed every so often. Halfway into the segment is an Infinite Ball power-up followed by six pyramid crystals. The player can use the power-up to destroy the pyramid crystals, although they can choose not to. The exit door is unique from the previous segments as it needs two buttons to open it instead of one.
