ExactLink - Gem Duo Puzzle is a number line puzzle with a gem theme. Every gem has a twin. Connect each gem pair with one line, and make that line exactly the right length. Not just connected. Exact. Formerly ExactLink: Number Line Puzzle. The puzzles and modes are unchanged; only the look is new. HOW GEM PAIRS WORK In ExactLink, you link two gems by drawing a path between them across the grid, and the path has to be the exact length. That's the whole idea: a logic puzzle about connecting pairs and counting every step. If you enjoy number link, connect-the-dots or line puzzle games, you'll feel at home, with one extra rule that changes everything. HOW IT PLAYS Exact length Each gem pair has a target length. Draw a continuous line from one gem to its twin. Too short or too long, and that pair isn't finished. Counters below the board, such as 7/7, track each gem pair as you play. Plus and minus tiles Some tiles carry a plus (+) or minus (−) value, such as +3. Passing through one changes the effective length of your line, so a long detour can be exactly right and a shortcut can fall short. Exact+ Exact+ is the mode built around exact length and +/− tiles. Every step counts. Classic Classic keeps the ExactLink feel with a more traditional flow, for when you want a cleaner line puzzle. Daily Quest A fresh challenge every day. Goals above the board Two goals are shown above the board. Fill all: every cell on the board must be filled. Match steps: the step count, that is the line length, must be correct. 1,000+ levels For short sessions or long runs. QUICK START FOR BEGINNERS 1. Find each gem's twin.
