Hashi vs Tree(3)

Connect bridges between islands to form one interconnecting path! Hashi are addictive bridge-connecting puzzles which were invented in Japan. Using pure logic and requiring no math to solve, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages. Each puzzle is based on a rectangular arrangement of circles, where each circle represents an island and the number in each island tells how many bridges are connected to it. The object is to connect all islands according to the number of bridges so that there are no more than two bridges in the same direction and all bridges are interconnected enabling passage from any island to another. To create a bridge simply swipe your fingertip between two islands. The game also features highlighting options, helping see in which directions bridges are allowed and whether an island segment is about to become isolated.

Tree(3) is a puzzle game built on one of the largest numbers in mathematics. You build a sequence of small trees, one at a time. Each tree may use one more node than the last, and its nodes come in three colors. There is one rule: no earlier tree may ever be found inside a later one. The moment a shape repeats, the sequence ends. Kruskal's tree theorem proves every such sequence must end. TREE(3) is how long the longest one could run — a number so large it cannot be written down in the observable universe. Your score is how far you get before the rule catches you. MAIN GAME — Pure TREE(3). Start from a single node and extend as far as you can. Every game is a new best-score attempt. PUZZLES — A position and a bank of candidate trees. Pick the ones that don't repeat an earlier shape. Three tiers; the skill is reading embeddings at a glance. DAILY — One puzzle a day, the same for everyone. Share your result without spoiling it. CHALLENGES — Invite a friend and take turns extending one shared sequence. The player who repeats a shape loses. LEARN — Short lessons on the rule, the trap in the first move, and why the game has to end. Tree(3) is free to play. Optional coins buy hints and avatars; ads can be removed with a one-time purchase. Nothing you can buy is ever won from another player.
