GridLinx vs Chess

GridLinx is a "connect" game that demands careful but quick thought in placing tiles together to build the largest connected structures. The more tiles you connect together, the higher the score. Stay alert though, there is a time limit on each round. So if your not quick enough you'll run out of time. When you build a connected structure you are credited both with game points and with more play time. So look for every chance to link your tiles. As you climb higher in levels you will notice that later levels require higher scores to advance. You will also notice new challenges that will keep you on your toes. So, get in the zone and put your puzzle brains on blast!

One move at a time. Chess gets clearer. Chess Master breaks every opening and endgame into four learning stages — Follow, Understand, Practice, and Challenge — so you meet each line four times in a row and the moves start to feel inevitable. Study the line, understand the reasoning, reproduce it from memory, then face an AI that plays the same opening against you — learning and real matches in one flow. Four-Stage Learning Flow 1. Follow — Tap each move in sequence, tracing the line by hand. 2. Understand — Watch the line auto-play while you read why each move wins. 3. Practice — Reproduce the sequence from memory, no hints. 4. Challenge — Play an AI that uses the same opening against you.
