Obstacles

Obstacles are elements that restrict or completely block cell movement and chain reactions. They play a key role in increasing difficulty and diversifying gameplay, adding extra mechanics players must consider when planning their moves.

Types of Obstacles

Obstacles can be passive or active, each affecting gameplay differently and creating unique level conditions.

Passive Obstacles

Passive obstacles do not interact with cells and remain in a fixed position. They create static barriers that players must navigate around. These obstacles cannot be destroyed or altered.

Examples of Passive Obstacles:

• Barriers – Stationary obstacles that do not move or react to interactions.

• Walls or Rocks – Block paths, preventing cell movement.

• Inactive Elements – Restrict movement but do not influence the game in any other way.

Active Obstacles

Active obstacles can change position, affect cells, or be destroyed/modified by the player. They introduce dynamic level changes and require a more strategic approach.

Examples of Active Obstacles:

• Moving Barriers – Block paths or alter chain reaction routes.

• Interactive Elements – Require special cells or boosters for removal.

• Adaptive Barriers – Change position based on player actions, forcing adaptation to new conditions.

Barriers

Barriers are a special type of passive obstacle. They are static, indestructible, and significantly impact game strategy. Cells cannot interact through barriers, limiting movement options and requiring additional logic to continue chain reactions.

Barrier Mechanics:

• Blocking Interactions – Cells cannot affect each other across barriers, requiring alternative routes or mechanics.

• Collision Bounce – Cells rebound off barriers as if hitting the game boundary or another cell.

• Fixed Position – Barriers do not move, adding strategic complexity when planning chain reactions and cell placements.
