About this app
Mathstack - Sequence Puzzle Love number puzzles? This one's different. Stack your way to victory by building sequences from 1 to 15 (or 15 to 1) across five colorful stacks to clear the board. The catch? There are more cards than space on the board. Think ahead, use your temporary slots wisely, and plan your moves to uncover the cards you need. Three difficulty levels to match your mood: - Easy (1-5) for a quick brain break - Medium (1-10) for a solid challenge - Hard (1-15) for number-crunching pros Simple to learn. Tricky to master. Impossible to put down. Terms of Service: https://hazerim.com/terms-of-service/ Privacy Policy: https://hazerim.com/mathstack/privacy-policy/
