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

Four 4s: A Brain-Training Math Puzzle! Is your brain feeling a little rusty lately? Introducing "Four 4s," the historic math puzzle born in Great Britain in 1881, now available as an iPhone app! The rules are very simple. In "Four 4s," you just arrange four "4"s and operator panels like +, -, ×, and ÷ to create an equation. Your challenge is to make the answer equal every number from 0 to 100. It looks easy, but it's deceptively deep. Can you use your full insight and mathematical mind to complete all the numbers? It's as easy as moving the panels with your finger, like "44 × (4 - 4) = 0"! But... can you make a number like 73? Loosen up your rigid thinking and have fun training your calculation skills and creativity. By the time you clear all the puzzles, your math brain will be more powerful than ever! ・ Simple Controls: Just arrange the panels as if you were playing with blocks. It's that easy! ・ Endless Challenges: Once you've conquered the "Four Fours," take on new challenges with "Four 1s" or "Four 3s"!

Verdict
The clearest difference is in-app purchases: Four 4s at none against Treequation's 1. Treequation's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price and device support there is nothing between them.
