SUMCRUNCHER
THE ONLY DAILY BRAIN GAME YOU NEED
A precision-designed numerical cognition exercise that trains four critical brain regions in under five minutes. Created by Guinness World Records Puzzle Master Timothy E. Parker, whose puzzles have reached over 180 million solvers worldwide.
TRAIN YOUR BRAIN DAILY
SumCruncher exercises four essential cognitive domains through continuous mental arithmetic. Unlike passive puzzles, your brain is computing every second — from first glance to final tile.
- Parietal Lobe — Numerical Processing
- Prefrontal Cortex — Strategic Planning
- Working Memory — Mental Tracking
- Processing Speed — Quick Calculation

Real peer-reviewed research supporting cognitive training through numerical exercises
Numerical Cognition Activates Multiple Brain Regions
Dehaene et al. demonstrated that numerical processing activates the intraparietal sulcus and prefrontal cortex, two regions critical for mathematical reasoning and executive control.
Every SumCruncher puzzle directly engages these regions through continuous mental arithmetic under time pressure.
Custom Cognitive Games Improve Attention & Memory
Anguera et al. at UCSF showed that custom-designed cognitive games improved attention and working memory in older adults, with effects lasting 6 months after training stopped.
SumCruncher's design targets these same cognitive systems through structured daily practice.
Working Memory Training Transfers to Fluid Intelligence
Jaeggi et al. found that working memory training produced measurable gains in fluid intelligence — the ability to solve novel problems.
SumCruncher's multi-number mental tracking is a direct working memory training exercise.
Cognitive Training Offsets Age-Related Decline
Park & Bischof showed that structured cognitive engagement helps maintain neural efficiency and can offset age-related cognitive decline.
Daily SumCruncher sessions provide the structured engagement pattern shown to protect cognitive function.
Working Memory Capacity Is Trainable
Klingberg demonstrated that working memory capacity can be increased through training, and these improvements transfer across different cognitive tasks.
Tracking multiple numbers toward a target sum is precisely the type of exercise shown to expand working memory capacity.
11,430-Participant Cognitive Training Study
Owen et al. conducted one of the largest cognitive training studies ever, showing that participants improved significantly on the specific tasks they trained on.
SumCruncher's 6 cognitive metrics track exactly this kind of task-specific improvement across sessions.
HOW IT WORKS
Three steps to a stronger brain
PLAY THE DAILY PUZZLE
5 minutes, 24 numbers, 1 target. Find all 9 sets of numbers that sum to the target. Your brain computes every second — from first glance to final tile.
GET YOUR BRAIN REPORT
6 cognitive metrics mapped to real brain regions. Processing speed, accuracy, working memory, strategic planning, pattern recognition, and memory consolidation.
TRACK IMPROVEMENT
See your brain get stronger over time. Sparkline trends, percentile rankings, cognitive age estimates, and detailed improvement deltas across every metric.
HOW SUMCRUNCHER TRAINS YOUR BRAIN
10 research-backed cognitive skills exercised in every session
Working Memory Capacity
Exercises the brain's ability to hold and manipulate numbers simultaneously.
Klingberg, Trends in Cognitive Sciences (2010)Processing Speed
Challenges rapid numerical evaluation under time constraints.
Dehaene et al., Science (1999)Numerical Fluency
Strengthens the brain's number sense through repeated calculation practice.
Dehaene, The Number Sense (2011)Strategic Planning
Requires multi-step problem solving to find target sums across rounds.
Anguera et al., Nature (2013)Pattern Recognition
Trains the ability to identify numerical relationships across sets.
Owen et al., Nature (2010)Attention & Focus
Demands sustained concentration across multiple rounds of play.
Park & Bischof, Dialogues in Clinical Neuroscience (2013)Cognitive Flexibility
Requires switching between different mathematical strategies mid-game.
Jaeggi et al., PNAS (2008)Error Monitoring
Builds self-correction skills through immediate feedback on wrong combinations.
Mental Stamina
Progressive difficulty across three rounds maintains cognitive engagement over time.
Decision Making Under Pressure
Time constraints simulate real-world rapid decision scenarios.
SumCruncher is designed as a cognitive exercise tool. While the game mechanics target skills associated with specific brain regions identified in peer-reviewed research, individual results vary. SumCruncher is not a medical device and does not diagnose, treat, or prevent any condition.

CREATED BY TIMOTHY E. PARKER
Timothy E. Parker is the world's most syndicated puzzle creator and the only person to hold the Guinness World Record for most published puzzles. His work appears in over 400 newspapers across 80 countries, reaching more than 180 million solvers worldwide.
With over 30 years of experience crafting cognitive challenges, Parker has developed a deep understanding of how numerical exercises engage and strengthen the brain. SumCruncher represents the culmination of that expertise — a precision-designed daily exercise that trains four critical brain regions in under five minutes.
Every SumCruncher puzzle is built on Parker's proprietary algorithm that guarantees mathematical elegance: 24 unique numbers, 9 solution sets, and one target — with the final four numbers always forming a perfect solution. No random generation. Every puzzle is a masterpiece.
