In the first game, the village of Yipe has been blocked in, and it is the hero's job to dig a way out while fighting monsters in the caves. After doing so, the final monster is revealed.
The second game introduces a larger world map, in which the first goal is to kill another monster in a cave. After doing so, the player will be told to retreive supplies from the nearby town of Maynard, which is accessed by one of two paths. Upon returning to the original town, the player finds that it has been attacked by aliens, who are residing in the western caves. This game is won upon defeating the aliens' boss.
The third game introduces several more plots, including the retreival of the King's missing stamp collection, and his daughters. Monster fighting continues as usual, but the player has a wider array of abilities, and far more regions in which to fight monsters.
In 2010, a fifth game (don't ask why there isn't a fourth) was released for the iPhone.
Tropes present in more than one of the games:
- Actually Four Mooks: In the second and third games, a single enemy sprite may turn out to actually be two or three enemies in a row. In III, they can even be of different types.
- Art Evolution: The art evolves considerably between games. The character is just a crude stick figure in the first game, while the next two games allow different and more polished character appearances.
- Beef Gate: All three games have places where a pathway is blocked off by an enemy. Sometimes, the enemy will even respawn if you leave that screen and go back.
- Difficulty Levels: All three games have normal, easy, and hard modes.
- Endless Game: After defeating the final monster, you can keep roaming around the world and fighting as many monsters as your heart desires.
- First Town: Yipe in all three games.
- The Goomba: In all three games, the first "monster" is a rabbit, which has very little HP and almost no attack.
- Hyperactive Metabolism: Instead of potions, random food items heal the Hit Points.
- Inexplicable Treasure Chests: They always have an item in them.
- Level Scaling: Higher levels mean tougher enemies will spawn (although the easy ones never stop spawning).
- Plunder: Killing a monster will always award money.
- Power-Up Food: Health is restored by consuming various types of food.
- Sdrawkcab Name: The spells are taught by a wizard named Epiy.
- Shareware: The second and third games won't let you access the entire world until you register.
- Spell Levels: In each game, your player can learn certain spells (typically healing or attack spells) upon leveling up and going to the spell shop.
- Wallet of Holding: There doesn't seem to be a limit for how much money a player can hold.
- Wicked Weasel: The second and third games have weasels as roaming monsters.
Tropes present in Quest Of Yipe I:
- Level Grinding: The enemies are so overpowered that you will need to do this a lot.
Tropes present in Quest of Yipe II:
- Cap: Strength, Dexterity, and Intelligence all cap at 25.
- Save Scumming: The help screen encourages you to save the game as often as possible.
- The Unpronounceable: The aliens' names.
Tropes present in Quest of Yipe III:
- Damsel in Distress: The King's daughters.
- Death Is Not Permanent: Unlike the previous two games, the player is sent to Hell upon reaching 0 health. After paying the gatekeeper a fee, the player is healed and returned to Yipe! The player can also choose to defeat the gatekeeper, but doing so will cause the player's health not to be replenished upon exiting Hell.
- Silliness Switch: You can choose to play on Silly mode, in which all of the weapons and armor become strange things like "thumbtack", "nail clippers", etc. (This was also the default mode of II.)
