Store description excerpt
Collatz Hailstone Link — a relaxing number-merge puzzle built on one of math's most famous mysteries: the Collatz conjecture (the "3n+1" problem). Drag and merge numbered tiles, watch each sum bounce through the hailstone sequence, and chase the highest — or lowest — final number you can reach. Easy to learn in seconds, deep enough to keep you coming back for a better score. HOW TO PLAY • Drag one tile onto another (or tap one, then another) to merge them. • The two values are added, then the Collatz rule is applied to the sum: - Even sum → divide by 2 (the tile turns blue) - Odd sum → multiply by 3 and add 1 (the tile turns orange) • Chain the same color in a row to build a streak bonus. • Keep merging until a single tile remains. Push that last value as high — or as low — as you can! FEATURES • Pure one-finger gameplay — merge with a drag or a tap. • 7 board shapes: Square, Hexagon, Triangle, and four hybrid layouts. • Three-part scoring: turn points, streak bonuses, and a final bonus based on your last number. • Undo your recent moves to plan the perfect chain. • Records screen — sort your runs by score, max value, final value, and date. • Global leaderboards via Google Play Games / Apple Game Center: compete on both High Score and Final Max. • Light & Dark themes. • English & Korean language support. • Play offline, anywhere — no account required. WHY YOU'LL LOVE IT A quick puzzle for a coffee break, a brain teaser for math lovers, and a satisfying score-chaser for everyone in between. Every board is a fresh little puzzle in number theory — no two runs feel the same. Merge the numbers. Ride the hailstones. Beat your best.
