Trickster Online (also known as Trickster: Links to Fantasy and Trickster Online Revolution) is a free, 2D isometric MMORPG developed by the Korean company Ntreev Soft.

Gameplay in Trickster is mostly click-and-fire based; movement, combat, and many other commands are all controlled by mouse. Gameplay also includes a few non-combat "systems". First, there is the Drill System, in which a player drills in certain types of terrain for items and EXP. Second, there is the Card Battling System, which sets two characters against each other in a game of cards, played with card items found by various means during normal gameplay. The game is currently released under all its versions as a free-to-play MMORPG but with a Cash Shop feature, also known in game as MyShop, that allows purchase of in-game items through real cash/credit charging.

There are two leveling systems: base leveling and TM leveling. Base leveling percentage is shown at the very top of the screen as a long yellow bar. When one levels up, he/she attains four points that they can allocate into 12 different stats (see below) in the "MyView" window. Base level is not only important for becoming more skilled in the 12 different stats but also in acquiring more powerful items. TM level percentage is displayed near the top of the "Skills" window and under the base leveling bar (as the green bar). When one levels up in this system, he/she gets one point that he/she can allocate into a skill, learn a skill with, master a skill, or simply save for later.

There is a special party system that exists within the game. The main benefit of the partying system is to multiply the experience points you receive up to 2.5 times. There are five types of parties. A normal party with six people (the most people one party can have) is a negligible 1.5 times your normal EXP. A type party consists of one type of class (i.e power, magic, sense, charm) and maxes out at 2.0 times the normal experience attained. Another type is beginner party, which does not double EXP gain. The final two parties max out at a 2.5 EXP multiplier. The first of the two is a royal party. A royal party consists of only one of each class (i.e one power, one magic, one sense, one charm) with another character of any job.

The final type of party is a special party which consists of all one gender (i.e male/female) with the exception of 2 opposite genders. Parties can only make their maximum EXP multiplier if everyone in the party is on the same map (ex. if there are six people in a royal party, it`d normally have a 2.5x multiplier, but if someone was on a different map, it`d only be a 2.0x multiplier until that person came back). The party leader can decide on the party settings how the EXP will be distributed and if items will be shared. (S)he can select if the EXP will not be shared, if it`ll be equally shared, if higher leveled players will get more EXP, or if it`ll be decided manually by the leader. (S)he can also decide if items can be picked up by anyone in the party if killed by anyone in the party or if people can pick up only the items they kill for. The latter of the two is much more popular, so there aren`t any disputes over party members. There is a bulletin board in-game where people can ask for members to join their party or ask to join a party. Partying makes leveling up much easier.
