SUM CRUNCH is designed to sharpen your mathematical intuition and speed. Developed by Guinness World Records puzzle master, Timothy E Parker, these exercises engage key areas of the brain to boost your Real World IQ.

The game challenges you to find combinations of numbers that add up to a specific target value. The quicker and more accurately you solve, the higher your score!

Benefits:

• Parietal Lobe: Enhances numerical processing and spatial reasoning.
• Frontal Lobe: Boosts problem-solving, planning, and decision-making.
• Temporal Lobe: Improves processing speed and short-term memory.
• Cerebellum: Refines cognitive flexibility and executive functions.

How to Play:

• Click on numbers in the grid to select them.
• The goal is to select numbers that add up to the TARGET value.
• Initially, you need to find TWO numbers that sum to the target (4 times). Once found, they will disappear, and you'll then need to find THREE numbers (4 times), and finally FOUR numbers (1 time) from the remaining grid that sum to the target.
• Use the HINT button if you get stuck. It will reveal some numbers, which are automatically selected and do not grant points.
• The SOLVE button will complete the current round for you, but it will significantly affect your score.
• Select a MODE (Benchmark or Advanced) to adjust difficulty.

Good luck, and enjoy boosting your brain power!
