ProofQuest
Logic puzzle adventure building proof-readiness through deductive reasoning puzzles, informal proofs, and mathematical writing
Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, praises, and patiently scaffolds learning. On-device AI personalizes the mentor's responses to your kid's progress — never connecting to a server, never collecting data.
#29B6F6 ProofQuest is a math reasoning adventure where you learn to think like a mathematician! Build chains of logic, assemble proofs from building blocks, and hunt for counterexamples to disprove false claims. Follow in the footsteps of Euler, who proved you cannot cross all seven bridges of Konigsberg, a
What's inside
Logic Chains
Drag and connect logical steps to build a chain of reasoning. Start with something you know is true, and connect it step by step to what you want to prove. Each
Proof Builder
Arrange given statements and reasons like puzzle pieces to construct a complete proof. You have all the pieces -- you just need to put them in the right order.
Counterexample Hunter
Someone claims something is always true. Your job is to find one example where it is NOT true. Finding a single counterexample disproves the whole claim! This i
Famous Discoveries
Explore mathematical discoveries like the Konigsberg bridge problem, the four-color theorem, and Ramsey's party problem. These real stories show why mathematici
