Level up your math skills with Treequation, a minimalist and innovative puzzle game featuring unlimited math puzzles represented as equation trees, and earn the prestigious Grandmaster title! Play anywhere, anytime: this game has no ads and doesn't require Internet. 45 full levels included in the free version. Like expression trees, equation trees represent operands as leaves and arithmetic operators as internal nodes. Your goal is to balance the tree by rearranging the movable nodes in a way that makes the equation true. Equation trees help you visualize the order of the operations as they trickle down from top to bottom, and they also provide an easy and intuitive way to rearrange the equation and gradually find your way to a solution. The full version features unlimited levels that provide an endless supply of mathematical brain teasers at different difficulty levels: Easy, Medium, Hard, and Extreme. Each puzzle has a general difficulty level from Easy to Extreme based on the topology of the tree. The actual complexity of the corresponding equation depends on the specific set of nodes in the tree and the hints used, and is measured in stars from 1 to 6. The general difficulty levels correspond to the following complexities: Easy -> 1 star, Medium -> 1-2 stars, Hard -> 3-5 stars, Extreme -> 5-6 stars. Solving a puzzle earns you one of 6 titles based on the number of stars awarded for that puzzle, ranging from Beginner for 1-star puzzles to Grandmaster for 6-star puzzles. Will you earn the coveted Grandmaster title and achieve the highest score? Treequation can be played completely offline, with no ads or microtransactions. There is only one in-app purchase (IAP) to unlock the full game with unlimited puzzles. Even without the premium content, the free game includes 45 full puzzles with a tutorial and the first two difficulties: Easy and Medium. With its unlimited math puzzles and endless challenges, Treequation can provide hours and hours of entertainment and relaxing brain training! Features: • Unlimited arithmetic puzzles that are procedurally generated, providing an endless supply of math challenges • First game of its kind, featuring a new kind of puzzle designed to be entertaining and educational at the same time • Four difficulty levels: Easy, Medium, Hard, and Extreme • Six titles to earn: Beginner, Intermediate, Advanced, Expert, Master, and Grandmaster • Granular scoring based on actual equation complexity and hints used • Minimalist design and simple yet challenging gameplay • Indie game, made by a solo developer • Playable completely offline, with no ads or microtransactions; single in-app purchase (IAP) to unlock the full game • 45 full levels and first two difficulties included in the free version Website: https://www.treequation.com End User License Agreement: https://www.secondentity.com/eula Privacy Policy: https://www.secondentity.com/privacy

数字は「いちばん近い魔物までの距離」。マインスイーパーの数字を再発明した、深海のソナーパズル。 酸素が尽きる前に真珠を集め、さらに深く潜るか、浮上して記録を残すか。 すべての盤面は「当て推量なしで解ける」ことを機械検証済み。運ゲーはありません。 【遊びかた】 ・タップ=ソナー照射(酸素-1)。空きマスなら数字は最寄りの魔物までの距離 ・距離のぶんだけ周囲は安全。ソナーの波紋が連鎖して海底をひらく ・魔物を踏むと酸素-4。長押しでマーキングして回避しよう ・真珠を見つけると酸素+3。層の真珠を集めきると「潜降ゲート」がひらく 【潜るか、還るか】 ・浮上すればスコア確定。潜降すれば真珠の価値x1.5、ただし魔物も増える ・酸素切れは緊急浮上、スコア半減 【特長】 ・全盤面がロジックで解けることを出題前に検証済み(初手も必ず安全) ・デイリーダイブ: 毎日世界共通の海。連続記録に挑戦 ・広告なし / データ収集なし / オフラインOK / 縦持ち片手 クラシックなマインスイーパーの推理が好きな人、Dragonsweeper系の判断が好きな人、どちらにも「初めてなのに懐かしい」体験を。
