At the Carnival/Gameplay

From StrategyWiki, the video game walkthrough and strategy guide wiki

At the Carnival is a puzzle game based on Cliff Johnson's experience with amusement parks. These puzzles are divided into various attractions, accessible from the menu at the top of the screen.

The first menu, "File", is used to load or save games.

This is followed by four menus, with the letters P, A, R, and K. Each of these submenus contains 10 attractions each, most of which can be completed in any order.

The next menu on the right shows the name of the current puzzle. Viewing this menu will show basic instructions on what needs to be done to complete the puzzle, in addition to providing a few puzzle-specific hotkeys.

When you launch the game, it will drop you directly into the first puzzle, which you can solve right away.
