You Don't Control
The Whole Board.
You Control A
Circle.

Calm Range: Radius Control is a minimal strategy puzzle where your influence exists only within a circular range. You move the circle across space, and you must position and adjust your radius to interact with them at the right moment.

BRIEF SUMMARY

What is this game about?

Calm Range: Radius Control is a strategy puzzle built around awareness and discipline. You move a circular range across a static, minimal field. Once you can see that circles can be influenced — your goal is to guide drifting elements to safety, align them correctly, or activate them — all within a limited number of moves.

It's not about speed.
It's about positioning.

CORE MECHANICS

You've gotta be smart about how you use your circle.

Move a circular range across the board
Adjust the radius size when needed
Interact only with objects inside the circle
Complete objectives within a fixed number of moves

HOW STRATEGY WORKS

Range is your only tool.
Expanding the radius increases coverage but consumes more of your limited move budget. Shrinking it gives tighter control but reduces reach.

  1. 1

    Do I control objects directly?

    No. You cannot grab or push objects manually. They move according to their own motion patterns. Your only influence is the circular range, which determines when interaction is possible. Basically, it all comes down to getting that circle positioned just right.

  2. 2

    Is the radius unlimited?

    The radius can be adjusted, but each adjustment counts toward your move limit. Expanding too often may leave you unable to finish the level. Efficient radius management is essential. Every change should have a purpose.

  3. 3

    What happens if an object leaves the range?

    Once outside your circle, the object becomes untouchable until it re-enters. This forces careful timing and planning. Sometimes waiting is more effective than constant repositioning. Patience is part of the strategy.

  4. 4

    Is the game difficult?

    The early levels are accessible and forgiving. As you progress, move limits tighten and object patterns become more complex. Difficulty grows gradually through logic rather than pressure. It rewards thinking ahead.

  5. 5

    Can I replay levels?

    Yes. Many puzzles allow multiple solutions. You can replay to improve efficiency and achieve higher precision scores. Optimization adds replay value without randomness.

  6. 6

    Is it suitable for short sessions?

    Absolutely. Most levels can be completed in a few minutes. The clean structure makes it easy to pause and return. It works well for quick focused sessions.
