Flow
Absorbed, continuous engagement produced by well-matched challenge and feedback.
23 mechanics carry this tag.
Advantage / Disadvantage
A modifier applied by rolling two dice instead of one and keeping the higher result under favourable circumstances or the lower under unfavourable ones, in place of a numeric bonus or penalty.
Aim and Recoil
The player steers a reticle onto a target in real time while spread, recoil, and sway perturb it after each shot, so whether a shot lands is decided by continuous pointing precision and recovery rather than by a roll.
Combo Systems
Successive actions executed within a timing window chain together, with each link enabling or multiplying the next, so a correctly timed sequence yields more than the same actions performed separately.
Constraint Logic Puzzles
A grid or arrangement must be filled so that every stated rule holds at once, such as no repeated symbol in a row, and the unique solution is reached by eliminating what the constraints forbid rather than by searching hidden state.
Cooldowns
After an ability is used it becomes unavailable for a fixed interval of time or turns, so the player rations powerful actions by timing rather than by spending a pooled resource.
Difficulty Settings
A rule-level parameter, chosen before play or adjusted by the system during it, scales enemy strength, resources, or margins for error so that the same content can be played at several levels of challenge.
Engine Building
Players assemble interlocking capabilities over the course of play so that each unit of input yields increasing output, converting early investment into late-game acceleration.
Fail Forward
A resolution principle under which a failed check must change the situation, introducing a cost, complication, or new development, rather than leaving the state as it was before the attempt.
Flashbacks
A player pays a cost to declare, after the fact, that their character took a preparatory action earlier, and the declared action is narrated as a brief scene and takes effect in the present situation.
GM Moves
The facilitator's interventions are codified as a named list of moves, triggered when a player misses a roll, when the table looks to the facilitator, or when a golden opportunity arises, and governed by a stated agenda and principles.
Lock-On Targeting
The player designates a target and the system then holds the camera, facing, or attacks on it until the lock is released or switched, so attacks connect without continuous manual aim.
Map Markers and Waypoints
The interface places icons on a map, minimap, or compass that mark objectives, points of interest, or player-set waypoints and updates them as state changes, so where to go is disclosed by the system rather than found in the world.
Match-Three
Pieces on a grid are swapped or dropped so that three or more identical pieces line up, the matched pieces are removed, and the grid refills, often producing chain reactions.
Parry and Dodge Windows
A defensive input succeeds only if it is entered within a short window relative to an incoming attack, negating the hit and often opening a counter-attack opportunity.
Platforming
An avatar traverses platforms and hazards by running and jumping under a fixed movement model, so progress depends on the timing and placement of each jump rather than on choosing among options.
Quest Structures
Play is organised into discrete assigned tasks, each with a framing, an explicit objective, tracked progress, and a reward on completion, so authored content is delivered and consumed one task at a time.
Rating and Matchmaking
A numerical rating moves after each game by transferring points from loser to winner in proportion to how unexpected the result was, and a pairing rule uses the ratings to decide who plays whom next.
Real-Time Play
Players act whenever they are able rather than in turns, so wall-clock time rations actions and speed of perception and execution determine who acts first and how often.
Referee Adjudication
The success and consequences of a declared action are decided by a designated neutral person applying judgement under published guidance, rather than by a table or randomiser alone, and that ruling is binding on play.
Rhythm Action
Notes shown ahead on a track or bar meet a judgement point in time with a piece of music, the player enters the matching input as each arrives, and every input is graded by its timing, so a song's result sums many graded timing tests.
Roll and Write
Dice are rolled, in modern designs usually once for the whole table, and each player records results on a personal score sheet, choosing where each is written under constraints that make later placements harder.
Scene Framing
Play is organised into scenes that a designated participant opens by stating where and when the scene is, who is present, and what is at stake, and closes by cutting away once the stake is resolved.
Tile Placement
Players add tiles to a growing map or personal grid under adjacency and matching constraints, so that the shape of the play area and its scoring features emerge from where each tile is put.
