Level

Clockwise from top left: Level endings of Super Mario Bros., Super Mario Bros. 2, Super Mario World and Super Mario Bros. 3.

All platformers have multiple levels (also called courses or stages) which contain obstacles, enemies, items, and the such. Mario, or other characters have to pass through these levels to get through the next. There are also levels that are hidden and need to get unlocked.

Levels appear in the Super Mario series. At the end of every level (except for castle levels) in Super Mario Bros., Super Mario Bros.: The Lost Levels, New Super Mario Bros. and New Super Mario Bros. Wii is a Flagpole (or a Red Flagpole if it is a secret exit in the New Super Mario Bros. games) and Fortress. At the end of Super Mario Bros. 2 are Hawkmouths. Most levels of Super Mario Bros. 3 end with Roulette Boxes, but Fortresses end with fighting Boom Boom and Airships pit Mario or Luigi against a Koopaling. Most levels of Super Mario World end with Giant Gates, but the castles end with fighting a Koopaling. Super Paper Mario has Star Blocks at the end of every sub-chapter after the chapter boss is defeated. Each game has a unique ending for its levels, although the outcome is always progression to the next level.
