Puzzle Solving

Puzzle Solving

Actions that can be solved through deductive or inductive reasoning.

Some goals in games do not have apparent solutions. This may be because players do not have all the game elements or information required, but can also be because the solutions require multiple actions performed consecutively and in an order that is not intuitive. In both cases, the activity players need to perform to find the solution is a form of Puzzle Solving. In some cases, the solutions may be drawing conclusions from the available information and, in others, testing hypotheses and rejecting impossible ones.

Example: The gameplay in Myst consists of solving a number of puzzles. Besides that, the only actions players can perform are to move in the environment that also moves players between the puzzles.

Example: Sokoban is a pure Puzzle Solving computer game where the only challenge the players have is to figure out how to push a number of boxes into the right parts of a maze.

Using the pattern

The prime challenge in designing a puzzle is to achieve the Right Level of Complexity for it. However, the difficulty of the puzzle can be modulated regardless of complexity by constructing the puzzles so that they can either be solved through reasoning or through manipulation, the latter being easier. Puzzles solvable by manipulation require that players have access to Direct Information, while those that can be solved through reasoning can make use of direct or Indirect Information. Puzzles that can be solved through manipulation of the game environment are a form of Configuration goal requiring Movement that can actually be solved by simply trying all combinations. Although this may cause players to do repetitious actions, it cannot be avoided even with Irreversible Actions or depletion of Non-Renewable Resources if players can perform Save-Load Cycles.

Puzzle Solving can start with complete or incomplete puzzles. Complete puzzles let players start with the Puzzle Solving at once, while incomplete puzzles require players to first complete Gain Information goals to gain the necessary Traces, Clues, or game elements. If players do not know if they have a complete or incomplete puzzle when they begin, they have to make Risk/Reward choices between trying to solve the puzzle or trying to look for more clues.

The design of Puzzle Solving has some additional possibilities depending on if the puzzles are part of Real-Time Games or Turn-Based Games. The Tension and Right Level of Difficulty of Puzzle Solving can be modulated in Real-Time Games by introducing Time Limits. Overcome goals can be based on Puzzle Solving in Real-Time Games, as players have to try and be quicker than the other players in finding a solution, or try to find opponents' Achilles' Heels while avoiding their attacks. For Turn-Based Games, many of the activities in Real-Time Games can be transformed into puzzles, for example, by having turn-based Movement creating Capture and Evade goals.


Completing goals of Puzzle Solving is a form of Stimulated Planning, as the challenge lies in finding the right combination of actions rather than performing the actions. This planning, although it may be partly externalized by arranging game elements, makes Puzzle Solving incompatible with Limited Planning Abilities. If players have restricted or no Game State Overview, Puzzle Solving requires Memorizing, while it promotes Experimenting if players have Limited Foresight but the game supports Reversability. Whatever the exact type of activity required to do the Puzzle Solving, it provides opportunity for Cognitive Immersion, and being skillful in solving puzzles is a form of Game Mastery.

Puzzle Solving has low Replayability unless the puzzle changes between game sessions. This can be achieved through the use of Randomness, but requires that the Randomness guarantee that at least one solution exists. The existence of several solutions can add some Replayability to games but primarily if they offer alternative developments of Narrative Structures or have Perceivable Margins compared to each other.
