The Trick House (Japanese: カラクリ屋敷Trick House) is located on Route 110 in Hoenn. It is owned by the Trick Master, who poses puzzling challenges to travelers. Those who wish to play his game must find their way through a maze-like puzzle at the back of his house. If successful, they will be rewarded.
The puzzles for Trick House are divided into three parts. First, the Trick Master is hiding somewhere in the first room of the house. In the Generation III games, the first three times the player enters the house, a small twinkle indicates the Trick Master's hiding place right away, but in later challenges and the Generation VI games the player must find him without any help.
Once the Trick Master is found, the player may enter the larger rear room through a passageway hidden behind the scroll on the wall. The rooms consist of some sort of maze with a gimmick to each of them, and each room also has Trainers and items (Mail in Generation III, locational specialties in Generation VI). The player must navigate through the maze to a second scroll, where they will obtain a secret code. Finally, the player must find the door to the Trick Master's room and write the code on it to gain access. Upon being found, the Trick Master will reward the player, and the player may take a shortcut passage out of the Trick House.
In Emerald, while the rooms in Trick House use mostly the same gimmicks in as in Ruby and Sapphire, the layouts of the rooms are each changed slightly. Trainers, items and the password scrolls are in different locations, and the maze's course changes as well. However, it is only their locations that differ; the items and Trainers in each room are the same in all versions except for the seventh puzzle (although the English name of one of the Trainers does differ in the fourth and eighth rooms).
In Ruby, Sapphire, and Emerald, players can take the challenges as they earn new GymBadges, but the final challenge cannot be taken until they defeat the Champion. In Pokémon Omega Ruby and Alpha Sapphire, there are only six puzzles; Badges are no longer required to start each puzzle, but some puzzles require specific HM moves to be used, which require specific Badges to use.
Each puzzle is only available once, and the puzzles must be completed in order. After all challenges are completed, the Trick Master disappears, leaving behind only a note saying he has gone on a journey to search for new tricks. In Omega Ruby and Alpha Sapphire, Mechadoll 5 also remains, taking off after the player interacts with it.
In Omega Ruby and Alpha Sapphire, the Trick Master's Mechadoll 3 appears at the start of some puzzle rooms. Mechadoll 3 sells Escape Ropes to the player at regular price. Escape Ropes can be used to exit the Trick House.
Mechadoll 3 only sells the player Escape Ropes in puzzle rooms 2, 3, 4, and 6. Once the player completes the sixth and last puzzle, they will no longer be able to purchase Escape Ropes from Mechadoll 3.
In Generation III, if the player is unable to accept the Red Tent or Blue Tent due to lack of space to store decorations in the PC, Mechadoll 5 will wait in the front room to hand over the reward on the player's subsequent visit, as the Trick Master himself has gone on a journey.
The second puzzle is a maze, but with a more confusing layout.
In Ruby, Sapphire, and Emerald, there are holes in the ground cannot be passed until the player hits a switch to extend a platform over them. However, the player cannot tell which switches cover which holes.
In Ruby, Sapphire, and Emerald, the third puzzle is a room full of alternating red and blue doors. Stepping on a switch opens all red doors and closes all blue doors, and stepping on a switch again will open all blue doors and close all red doors. The entrance to the room, and some switches, are covered by rocks that can be shattered with Rock Smash. No wild Pokémon can appear from these rocks.
In Omega Ruby and Alpha Sapphire, the room is dark maze that can be illuminated using Flash, but it isn't necessary to use the move to proceed. At the tail end of the maze is a stairway hidden by the maze walls. Using the stairway will allow the player to move south underneath the maze to a small area where the password scroll is hidden.
The fourth puzzle is a room full of boulders that must be pushed aside using Strength. However, due to the close quarters, pushing boulders the wrong way can block certain paths. In Japanese Emerald, two passageways were narrower. In Omega Ruby and Alpha Sapphire, there are no Trainers in this room.
Trainers with a PokéNav by their names will be registered in the Trainer's Eyes or Match Call function after the first battle, and may have a rematch with the player with higher-level Pokémon.
The fifth puzzle is a room with a sequence of five Mechadolls that will ask the player questions of escalating difficulty. They each react to seeing the player or being interacted with as if they were Trainers, but instead of challenging the player to a battle they ask a question. Answering correctly allows the player to continue; answering incorrectly sends the player back to the start of the room, such that the player has to answer each of the Mechadolls' questions again. Each Mechadoll will ask the player one question from a pool of three randomly.
In Ruby, Sapphire, and Emerald, the sixth puzzle is a room full of rotating gates like those found in Fortree Gym, but arranged in a more confusing pattern. As with Fortree, the player must walk through the gates in certain combinations to advance through the room. There are several Trainers in this room.
In Pokémon Omega Ruby and Alpha Sapphire, the room is full of spin tiles (like puzzle 7 in the Generation III games). This is also the final puzzle in these games. There are no Trainers in this room.
In Ruby and Sapphire, the seventh puzzle is a room filled with spin tiles, similar to those in Mossdeep Gym. The player must navigate the maze of spin tiles and pull switches to change their directions to advance through the room.
In Emerald, the seventh puzzle is a room full of Trainers standing on spin tiles that rotate when switches are triggered.
The difference between the puzzles is likely due to Mossdeep Gym being redesigned in Pokémon Emerald.
This puzzle does not appear in Pokémon Omega Ruby and Alpha Sapphire.
In Ruby, Sapphire, and Emerald, the eighth puzzle is a room is divided into two areas, an upper and lower area. Both are made up primarily of polished floors lined with pots. Similar to ice tiles, stepping on the polished floor will send the player sliding across it until they hit an obstacle. The player must navigate their way across both floors to advance. This is the final puzzle.
This puzzle does not appear in Pokémon Omega Ruby and Alpha Sapphire.
The King of Tricks hosts an annual contest at his Trick House in Mauville City. The competitor who overcomes the Trick House's various rooms receives a year's supply of Pokéblocks. These obstacles vary each year, and they include rope swings, log walks, and confusing mazes.
