## What is Isoline?

Isoline is a block puzzle with a sense of place.

Drag pieces onto an 8×8 grid and clear full rows and columns — you know how this works. But every game in Isoline is played over the topographic contours of a real location somewhere on Earth. As you clear lines, the place gives itself away: first its coordinates, digit by digit, then its name. Mt. Fuji. The Grand Canyon. A fjord in Norway you've never heard of. Keep playing and your Places collection fills in, one landscape at a time.

No timers. No lives. No ads — ever. Just a quiet grid, soft earth-tone palettes, gentle haptics, and the slow satisfaction of figuring out where in the world you are.

THREE WAYS TO PLAY

• Discovery — the endless mode. Chase a high score while uncovering new places; choose which location you want to reveal next. 
• Daily Challenge — everyone in the world gets the same pieces today. One run, one score, one leaderboard. Keep your streak alive. 
• Puzzle — a pre-filled board and a fixed set of pieces with a guaranteed solution. Fill the board to solve it.

A WORLD TO COLLECT

100 real places across 11 themed packs — Iconic Peaks, Ring of Fire, Carved & Canyon, Islands & Coastlines, Sacred & Meditative, Craters & Calderas, Karst & Spires, Deserts & Dunes, Fjords & Coasts, Waterfalls & Gorges, and the Pacific Northwest. Each place is drawn from its actual elevation contours. Start with Mt. Rainier, Mt. St. Helens, and Mt. Hood for free, and unlock more packs whenever you like. Any place you've discovered can become the backdrop for your menus.

MADE TO FEEL GOOD

Isoline is built natively for iPhone and iPad: springy piece handling, line-clear particles that follow the terrain, Core Haptics feedback, and synthesized sound that respects your silent switch. Earth-tone palettes in light and dark. Reduce Motion honored throughout.

FAIR BY DESIGN

The game is free and complete. Optional purchases unlock additional place packs (or everything at once) and a one-time Continue after game over. There are no ads, no energy systems, and no subscriptions.

Where will your next line take you?
