Aufbau principle

Aufbau principle is a classic action-adventure platformer video game where the user attempts to catch as many things as they can to fill up the shelf from bottom to top. The highest score wins. Electrons, being the main source of all video games, were so inspired that they switcheroo'd their atoms' subshells to copy the game mechanics. However, the Pauli exclusion principle allows for only up to two thingamajigs at a time in each shipping container. The devs have yet to file a cease and desist letter for plagiarism.

Easter eggs

When the sneaky Brisk Balloon is hit, it activates Make It Rain Mode, where the objects fall down in a rapid fire manner at a rate of 3 objects/second. This challenges the player to test their reflexes. Not one single player has managed to catch the clever sac of rubber, and so Make It Rain Mode has never been activated in the game's history.

When the player has three wooden blocks next to each other, the shelf turns into a serving pan. This enables the blocks to be stacked like in Jenga, which presents the hidden award. More noticeably, a single fork will cause the same abnormality, as the fork's hidden award is presented when the player successfully stacks a Sierpiński triangle.

A tetromino appearing out of the blue will cause the game to instantaneously switch into Tetris when stacked.
