## What is Summable?

Swipe. Merge. Hit the number.

Summable is a calm, clever math puzzle. Every level gives you a grid of numbered blocks and a goal. Swipe across a row, column or diagonal to merge blocks into their sum. And keep building until one block shows exactly the goal.

Sounds simple. It isn't for long.

HOW IT WORKS
• Merge equal numbers: 1 + 1 + 1 becomes 3
• Build chains: 1, 1, 2, 4 merges into 8 in a single swipe
• Find the star blocks: a * multiplies everything on each side of it
• New blocks fall in from the top – plan where they land
• Some levels limit your moves. Find the smartest path.

WHY YOU'LL LIKE IT
• [N] hand-made levels, from first swipe to real brain-benders
• No timers, no pressure – think as long as you want
• Restart any level instantly
• Works offline
• Light and dark mode
• Great for practicing mental math, for kids and adults alike
