Can You Spot the Right Cluster?
Each Cluster Sum puzzle shows a target number and several number clusters - but only one cluster contains the correct combination.
Your job is to find the group of numbers inside a single cluster that adds up exactly to the target sum. Every other cluster is a clever distractor: close, believable, and intentionally misleading.
With unique solutions, smart design, and multiple puzzle styles, Cluster Sum delivers a satisfying logic challenge that keeps your brain engaged from start to finish.
One cluster is correct. Find it.
