MintForge
Financial math game where financial scenarios ARE the math problems — compound interest, percentage markup, budgeting, loan amortization, stock market simulation
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.
#FFA726 MintForge teaches you math through money! Run a virtual savings account to learn compound interest, set prices in a school store to learn percentages, and manage a budget to learn about expenses and income. The financial scenarios ARE the math problems, so every calculation has a real purpose.
