Cointo

Four-in-a-row, with a twist

$0.99 · Designed for iPad. Not verified for macOS.

Cointo is a fast, two-player strategy game from the Society of the Hourglass, designed to be played on a single iPad. Think four-in-a-row — except your opponent chooses which coin you have to play. HOW TO PLAY Sixteen unique coins share a 4×4 board. Each coin has four attributes: color (gold or silver), size (small or large), shape (square or circle), and fill (logo or blank). Players take turns placing the coin their opponent picked for them, then choosing the next coin their opponent must place. Line up four coins that share at least one attribute — in a row, column, or diagonal — and you win. Fill the board with no match and it's a draw. Every coin is shared, so every choice cuts both ways: hand your opponent a safe coin, or set a trap and hope they miss it. FEATURES • Play solo against a computer opponent, or pass-and-play with a friend on one iPad • 16 unique coins, 4 attributes, endless combinations • Play as figures from the Society of the Hourglass — Harriet Tubman, Nikola Tesla, Joan of Arc, Hypatia, Blackbeard, Zenobia, Sacagawea, Marie Curie, Leonardo da Vinci, and more • Built-in rules so new players can learn in a minute • Rounds take just a few minutes • No ads, no accounts, no internet required
