Logic first
The experience is designed around meaningful deduction rather than turning the core challenge into random guessing.
oorio Mines takes a familiar puzzle and rebuilds it around logical solving, progressive challenge, reflection, and training—while keeping the energy of a real game.

The experience is designed around meaningful deduction rather than turning the core challenge into random guessing.
Difficulty and progression are structured so the player can feel the difference between simply playing more and actually solving better.
Review helps turn a finished board into feedback: what worked, what slowed you down, and what can improve next.
Training can focus attention on patterns and techniques that deserve more practice.
oorio Mines is structured as more than a sequence of boards. Play, progress, review, and training are designed to connect so a finished puzzle can become useful feedback.
Solve a logically meaningful board with the tension and speed of a real game.
Move through staged challenge rather than repeating one flat difficulty forever.
Look back at a solve to understand what helped, what slowed you down, and where reasoning became inefficient.
Use that feedback to focus practice on patterns and techniques that deserve more attention.
Stages and longer-term progression can make improvement visible without turning the game into a checklist.
Review can surface hesitation, inefficient paths, missed deductions, and technique patterns without pretending a game score is a clinical measurement.
Training can focus on recurring weaknesses instead of simply serving another random puzzle.

WHY MINES
oorio Mines goes beyond finishing a board quickly. Use logic instead of guessing, face harder problems, review how you solved them, and use each game to prepare for the next. We are redesigning minesweeper as a brain-training journey.
WHAT MAKES IT DIFFERENT
A few difficulty levels · repeated boards · time and win/loss focus · finish and move on
Six stages inside each Planet · Puzzle Families and Variants · Review · Training · logic-first solving
FOR EVERY LEVEL
Basic logic: understand numbers and find certain clues.
Compare multiple clues and narrow the possibilities.
Work with combined conditions and longer chains of reasoning.
Start at the right level, take on complex Families and Variants, and Review your solving.
This is not simply easy minesweeper made harder,but minesweeper that keeps challenging players at different skill levelsover time.
PLANET SYSTEM
Planet 1 is the first complete progression, moving from basic judgment to comparing multiple clues, narrowing possibilities and sustaining longer reasoning. It does not simply add more cells and mines; each stage changes the depth of judgment and reasoning, while multiple Puzzle Families and Variants let players apply similar thinking principles in different situations.
Experienced players are intended to find an appropriate starting point instead of repeating every beginner step.
PLAY · REVIEW · TRAIN
Observe and decide for yourself as you solve.
Turn hesitation points and decision flow into feedback for the next game.
Focus on patterns and techniques that deserve more practice.
Play → Review → Training → Play
DIFFERENT AGES
The game repeatedly calls on attention and observation, logical reasoning, working memory, planning and order, and checking mistakes. The goal is to create time for independent thinking in a form different from schoolwork.
In a day where AI and automation make many decisions for us, the game provides active time to focus, compare conditions and think about the next move.
We aim for an experience that can be observed, checked, remembered and judged at one's own pace. Controls, text size, difficulty and pacing can evolve for different users.
This is not a medical device or dementia prevention or treatment program. No specific cognitive effect is guaranteed.
WHY BRAIN GAMES IN THE AI AGE
AI is a powerful tool that expands human possibilities. At the same time, people still need experiences that actively use observation, memory, comparison, reasoning, planning and judgment.
In an age when machines think more for us,
how will we use our own minds?
This is not training to compete with AI,but an experience for continuing to use the human mind actively while living alongside AI.
PLANET 2 AND BEYOND
After Planet 1, expansion will not simply mean bigger numbers. Each Planet is intended to have distinctive constraints, decision patterns and goals.
The Foundation. The first complete six-stage progression.
New reasoning rules and distinctive challenges.
New worlds that ask you to think in different ways.
