## What is Loop 16 Puzzle?

A new twist on the classic 16-puzzle! Unlike traditional puzzles with an empty space, this puzzle uses all 16 pieces. Slide rows or columns—as pieces disappear off one edge, they reappear on the other!

【How to Play】
- Objective: Arrange tiles 1–16 in numerical order.
- Loop Slide: Swipe any row or column. The grid loops infinitely.
- Level System: Level 1 requires 1 move to solve. Completed it to unlock the next level!
【Features】
- Pick Your Level: Use the "+" and "–" buttons to start from any level up to your [Best] + 1.
- Auto-Save: Your [Best] level is always saved so you can resume anytime.
- Easy Menu: Long-Press the screen to quit the current puzzle and Start Over w/ Assist, challenge a different issue, or reset your [Best] level.
- Assisted Practice: Use "Start Over w/ Assist" to help solve difficult puzzles. Note: Clearing a puzzle with Assist will not increase your level—use it to hone your skills!

Challenge yourself and see how many moves ahead you can think!
