10th Corpse released in 2020. It is a hybrid of Match-Three Game and Hidden Object Game genres. In it, you play as a detective who has been told to investigate a strange card Madame Vinterfragen received which reads "You'll be the 10th Corpse!". He is meant to solve the mystery behind the card by talking to the eccentric guests and investigating.
The game tends to focus on Match 3 gameplay, but switches to other styles of gameplay when characters decide to play one of Professor Arkadiusz's games. Every few levels or so, the story progresses.
This game provides examples of:
- Arc Words: "Somewhere a candle has been lit.", which appears every time you clear a few levels.
- At Least I Admit It: If you admit to Thelma that you're just another intruder in her kitchen, she'll admire the fact you admit it.
- Beast Man: The second character in 9th Corpse appears to be some kind of wolfman wearing a suit who can speak.
- Brutal Honesty: Arkadiusz expects honest feedback related to his games, so you should tell him that they're terrible when he asks for it.
- The Butler Did It: Lewis assumes the butler, Madison, is the culprit, since it's always the butler.
- Disc-One Nuke: One of the power-ups lets you deal 50 damage to an opponent in a match 3 battle. The first few opponents don't even have that much HP, so it's an easily-available insta-kill which is still useful later on, as long as you don't mind losing a star from not using power-ups.
- Game-Breaking Bug: It's possible for a key to get stuck by overlapping with another piece in level 54, rendering it unwinnable.
- Game Within a Game: Professor Arkadiusz makes quite a few games, like Arkadiusz Kombi!, a Puyo Puyo-styled game, 9th Corpse, a game that seems to be a prequel to this one, and Arkadiusz Boxtrap, a game where you trap skulls in 3x3 boxes. Characters either find them enjoyable or confusing and you often have to play them to progress the story.
- Hello, [Insert Name Here]: You can insert your name which the characters will refer to, though it's in all-caps for some reason.
- Hereditary Curse: When a member of the Vinterfragen family finds a certain card, they're bound to be killed. Baroness Lucy Vinterfragen got stabbed to death in 1657 after receiving the "1st Corpse" card, novelist Edward Vinterfragen found a card among the manuscript he's been working on and became the "2nd Corpse", and so on. Madame Vinterfragen has received the "You'll be the 10th Corpse!" card and sees it as a curse.
- Loads and Loads of Loading: The loading screens may take a few seconds at most, but the game has to load every time you switch rooms (which sometimes you can only be in for one line of dialogue) or start a new level.
- Manchild: Arkadiusz tends to want to eat junk food, wears an orange shirt with the words "Game designer" on it, and overall sees video games as the main thing of life, despite being an adult who appears to be middle aged.
- Only Smart People May Pass: You may be asked questions about things in the game, like how many shovels were in the first room, or more general knowledge, like how many sides a hexagon has. Answering correctly increases your stats.
- Power-Up: You have six power-ups that are charged as you play. Their effects range from destroying tiles to helping with match 3 battles.
- Recursive Canon: Professor Arkadiusz is a Match 3 game designer. The title screen for 10th Corpse can be seen at the back of his room, suggesting he had designed it while being in it.
- RPG Elements: By answering questions correctly, your stats increase. These include HP and Attack for Match 3 Battles and power-up recovery rate for all match 3 games.
- Scoring Points: You earn points when you break pieces or pass certain puzzles.
- Warm-Up Boss: Level 21 is the very first Match 3 battle. Arkadiusz has 30 HP and deals 2 damage with each attack. Nevertheless, it's possible to have 110 HP and 20 attack by this point, making him a pushover, and he shouldn't be much of a challenge if you haven't answered questions correctly anyway.
