[3] Items of garbage in the game start small, with things like pencils, pens, staplers, erasers, and other office trash.

[4] Every so often a special piece of trash, called mottainai (pronounced mo-teye-neye, meaning a sense or regret for waste in Japanese) will fall and must not be compacted (items which are assumed to have been thrown out by mistake, jewelry for example).

[1] The scoring system is divided into two categories depending on how the player chooses to dispose of or compact their garbage to progress through the stage: Eco (Ecological) versus Ego (Egotistical).

If the player groups together biodegradable items so that they decompose naturally and smashes much of their garbage into smaller, more compact pieces, their Eco rating will rise.

Three versions, ranging in difficulty from Sweets (easy), Main Dish (medium), and Hellish (hard, must be unlocked) can be chosen to play.
