Life is full of limits. The goal isn't just to choose—it's to optimize. Maximize value under constraints.

You have limited resources (time, money, space). You need the best possible outcome.
Constraint Crusher is a logical reasoning game focused on constraint satisfaction and optimization problems. These problems appear throughout competitive exams, technical interviews, and real-world business situations.
The game presents puzzles where multiple conditions must be satisfied simultaneously. You must systematically explore possibilities, eliminate invalid options, and find solutions that meet all requirements - the exact skillset tested in CAT LRDI and consulting interviews.
The game features diverse constraint problems:
Problem Types: • Linear Arrangements: Order items based on given constraints • Circular Arrangements: Position elements around a circle with conditions • Grouping Problems: Divide items into groups satisfying multiple rules • Scheduling: Assign tasks to time slots meeting all requirements • Resource Allocation: Distribute limited resources optimally
Difficulty Levels: • Simple two-constraint problems • Medium multi-constraint with unique solutions • Hard optimization under constraints • Expert problems requiring backtracking
Identify all limitations and rules that must be satisfied.
Determine what can be changed and what is fixed.
Systematically explore options that satisfy all constraints.
Among feasible solutions, find the best one for the given objective.
Constraint Crusher develops essential analytical abilities:
Multi-Constraint Reasoning: Holding multiple conditions in mind while exploring solutions.
Systematic Elimination: Methodically ruling out impossible options rather than random guessing.
Backtracking: Recognizing dead-ends and efficiently returning to explore alternatives.
Optimization Thinking: Finding best solutions, not just any solution - key for business decisions.
Pattern Recognition: Identifying common constraint structures speeds up solving.
This game directly targets reasoning in competitive exams:
CAT LRDI: Arrangement and grouping puzzles are LRDI staples. Constraint Crusher builds speed and accuracy.
GRE/GMAT: Logical reasoning sections include constraint-based questions.
Consulting Interviews: Case studies often involve resource constraints and optimization.
UPSC: Preliminary reasoning includes arrangement-type questions.
Constraint Crusher benefits analytical problem-solvers:
• CAT/MBA Aspirants: Master the most common LRDI question types • Consulting Candidates: Build structured problem-solving skills for case interviews • Operations Professionals: Strengthen optimization and planning abilities • CS Students: Understand constraint satisfaction programming foundations • Anyone (16+): Develop systematic logical thinking
The game applies constraint satisfaction research:
Constraint Satisfaction Theory: Based on CSP solving algorithms and heuristics from AI research.
Bounded Rationality: Strategies account for human cognitive limitations in complex problem spaces.
Worked Examples: Research shows that analyzing solved problems before practicing improves learning.
Deliberate Practice: Progressive difficulty with immediate feedback optimizes skill development.
Start by identifying the most restrictive constraints - they eliminate the most options
Draw diagrams for arrangement problems - visual representation reduces errors
Look for definite placements first before considering conditional ones
When stuck, try assuming a position and trace the consequences
Practice with timer to build exam-appropriate speed
