Math Spark Games vs Logic Blocks Go

8 strategy games. Zero ads. No internet required. MathSpark is a collection of classic and lesser-known abstract strategy games -- each one hand-crafted with three difficulty levels, Game Center leaderboards, and pass-and-play multiplayer. Whether you're sharpening your logic on a commute or challenging a friend across the table, every game is designed to make you think. **THE GAMES** • TEEKO: Place and slide 4 pieces to form a line or square on a 5×5 board. Simple to learn, deceptively deep. • DOTS & BOXES: Draw lines between dots to claim boxes. Complete the fourth side and you score, but give your opponent a chain and you'll regret it. Customizable grid sizes from 3×3 to 6×6. • SIM: Six dots, fifteen lines, one rule: don't complete a triangle in your color. A game of pure avoidance where every move tightens the trap. • BUNCH OF GRAPES: Place your fly on a grape, then hop to adjacent grapes. Each grape you leave is eaten forever. Trap your opponent or starve trying. Randomized boards keep every game fresh. • DANDELIONS: An asymmetric battle: one player plants flowers, the other blows wind to scatter seeds. Can the Dandelion fill the board before Wind runs out of directions? • CONNECT 4: Drop discs into columns and race to get four in a row: horizontally, vertically, or diagonally. • AMAZONS: Move your queens and shoot burning arrows to destroy squares. Territory shrinks with every turn. The last player able to move wins. **FEATURES** • 3 difficulty levels per game: Easy for casual play, Hard for a real challenge • Game Center leaderboards and achievements • Pass-and-play multiplayer on one device • Solo practice mode to explore freely • Built-in rules for every game: tap the info button anytime • Win/loss stats tracked per game and difficulty • Dark mode support • No ads, no in-app purchases, no account required
