Treequation vs sudoku.studio

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.

Studio Sudoku combines clean minimalist visuals with robust logic tools across three 9×9 variants: Classic (standard 3×3 boxes), Diagonal (both main diagonals must stay unique), and Killer (irregular cages must add up to fixed sums). Choose easy, medium, or hard difficulty, switch between digits or pencil marks either via a dedicated toggle or by holding a cell, and rely on the highlight-equals option to instantly show every matching number. Hints are limited, mistakes penalize your score, and the progress bar shrinks as time elapses or errors pile up—so you always know how much is left. Settings let you pick the interface language, force dark/light mode or follow the system theme, and toggle tactile feedback for notes. Detailed statistics capture wins, losses, streaks, and variant breakdowns while the goals board tracks milestones like diagonal mastery or Killer victories. With animated gradients, contextual dialogs, and adaptive layouts, Studio Sudoku keeps advanced solving satisfying without sacrificing polish.
