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

Just Star Battle is a quiet take on Star Battle. The board is divided into regions of irregular shapes. Place exactly the required number of stars in each row, each column, and each region — with one extra rule: no two stars may sit in neighboring cells, including diagonally. Three small rules govern the whole game: 1. Tap a cell to cycle empty → × → star. The × is a player annotation for "definitely not a star"; only stars affect the solution. 2. Place exactly k stars in every row, every column, and every region. 3. No two stars may touch — including diagonally. Simple rules, plenty of room to think. CONTENT — Over 1500 hand-curated puzzles, every one verified to have a unique solution. — Two phases of play. First, work through the campaign — a steady curve from gentle 5×5 starters up to dense 14×14 / 3-stars-per-region boards. Then Free Play opens: pick any difficulty and keep drawing from the library at your own pace. PART OF JUST PLAY Just Star Battle is the sixth game in the Just Play series, after Just Sudoku, Just Puzzle, Just Yin Yang, Just Stack, and Just Hanoi. The series shares one design philosophy: classic logic puzzles, patiently rebuilt, in a quiet voice. No ads, no streaks, no engagement loops. The interface stays out of the way; the puzzle does the talking. PLAY YOUR WAY — Tap to cycle through the three cell states. No drag, no long-press. — Restart any level at any time — never costs you anything. — Region tints help your eye partition the board on the larger grids. — Soft haptics that confirm your touch without shouting. PRIVACY BY DEFAULT Just Star Battle does not collect any personal data. It works completely offline. There is no account to create, no email to enter, no servers to talk to. Your progress lives on your device, and on iCloud if you choose to sync it. FULLY LOCALIZED Available in: English, 简体中文, 繁體中文, 日本語, 한국어, Español, Français, Deutsch, Italiano, Português (Brasil), Русский, العربية. For people who love the puzzle itself.
