If you love Sudoku but are looking for a deeper challenge, or if you simply enjoy games that give your brain a real workout, Calcudoku is the ultimate logic puzzle. It combines the grid-filling deduction of Sudoku with simple arithmetic, creating a deeply satisfying balance of mental math, strategy, and problem-solving. Whether you want to sharpen your focus, keep your mind agile during a quick break, or master complex logical deduction, Calcudoku offers endless replayability for beginners and puzzle veterans alike. --- WHAT IS CALCUDOKU? --- Also known as Mathdoku or KenKen®, Calcudoku challenges you to solve a grid using logic and arithmetic: • Grid: Fill an N x N grid so that every row and column contains the numbers 1 through N exactly once without repeating. You choose the grid size to solve, anywhere from a 3x3 to a 9x9. • Cages: Outlined groups of cells (cages) each display a target number and an arithmetic operator. • Math: The numbers in each cage must combine using its operator (+, −, ×, ÷) to hit the target. Numbers can repeat within a cage as long as they stay in different rows and columns. It’s the ultimate combination of mental math, pattern recognition, and pure deduction. --- THE SMART DIFFERENTIATOR --- Many puzzle apps ruin the fun when you get stuck by simply filling in a random cell for you when requesting help. Our app takes a different approach: it teaches you how to solve it. If you hit a wall, our built-in helper analyzes your exact grid state and explains the logical next step. The engine guides you through genuine deduction strategies—showing you how to cross-reference overlapping cages, prune cell candidates, and leverage your notes so you can solve the grid completely on your own. --- KEY GAME FEATURES --- • Intelligent Explanations: Step-by-step guidance focused on note-taking, elimination strategies, and candidate pruning rather than giving away answers. • Optional Auto-Notes: The settings tab provides the option to jump into a puzzle with the initial candidate notes based on cage arithmetic. Skip the mundane and get right to the logic! • Smooth Input: Rapidly input answers and edit candidate notes with an intuitive, fluid UI built for mobile screens. • Complete Arithmetic Variety: Play grids featuring addition, subtraction, multiplication, and division. • All Skill Levels: Progress from quick 3x3 warmups to grueling 9x9 logic grids. • Polished Interface: Full native dark mode support, crisp typography, and seamless offline play - no Wi-Fi required. Master the grid, elevate your deduction skills, and train your brain with a game that actually makes you a better solver.

Soothe Quest is a match-3 puzzle game designed from the ground up for people living with chronic illness and chronic pain — and for anyone who wants a game that respects their energy. Created by a rheumatologist who lives with chronic pain himself, Soothe Quest is what a "cozy game" should actually mean: genuinely engaging puzzles, with every pressure mechanic deliberately removed. WHAT MAKES IT DIFFERENT • A rest-friendly streak — it counts the days you show up, forgives rest days, and losing never breaks it. Consistency over heroics. • The Zen Garden — a no-fail sanctuary mode. No moves, no timer, no losing. Just match, breathe, and watch your garden grow. • Tiny Wins — one-minute levels for low-energy days that still count toward your daily gentle goal. • A gentle boost — struggling with a level? The game quietly offers a little extra room, no judgment. • Real encouragement — after each level, a line from The Resilient Path: Modern Strategies for Living with Chronic Pain, written by the game's creator. Save the words that help to your Comfort Journal, and share them as beautiful quote cards. • The Calm Corner — guided box breathing and soothing rain or wave soundscapes, built right in. • Comfort & Access — larger gems, tap-only controls for steady hands, colorblind-friendly shapes, and softer effects for light-sensitive days. • A stretch check-in that gently suggests a break after a while — because a game made for your wellbeing shouldn't pretend time doesn't pass. A REAL GAME, TOO 54 handcrafted levels across six dreamlike worlds, ice and stone puzzles, line blasters, bombs and rainbow gems, chunky satisfying combos, an endless Rift for when you want depth, a prize lantern, and eight cosmetic gem skins. All music and sound is gentle and original. OUR PROMISES Nothing in Soothe Quest punishes you for resting. There are no expiring rewards, no fear-of-missing-out events, and no ads.
