Arukone Logic
Connect matching number pairs with clean lines and fill each puzzle grid without crossing paths.
Tested by NumBlocksGen
What we reproduced
- The level selector exposed levels 1 through 5 plus random and seed-based puzzle options.
- Opening level 1 produced three matching number pairs arranged on a dot grid.
- The board displayed timer, difficulty, reset, erase, bookmark, and back controls around the puzzle.
Known limitation: Drawing clean paths with a pointer is easier on a larger screen than on a narrow mobile viewport.

Source instructions say to draw lines between equal number pairs. The project includes 81 levels with unlockable difficulty progression. Source notes mention cloud progress for eligible Scratch users and that medium/hard solutions fill all grid squares.
Editor's Guide
Our test captured level 1: three matching number pairs on a dot grid, with timer, difficulty, reset, erase, bookmark, and back controls visible around the puzzle.
The rule (per source) is connect matching numbers without crossing lines. On medium/hard (per source), solutions must fill every square, adding spatial completeness constraint.
With 81 levels (per source), this provides substantial content with clear difficulty progression through unlockable tiers.
- Students who enjoy logic puzzles like Sudoku or KenKen (our suggestion for grades 4-8)
- Players wanting significant content (81 levels per source)
- Developing constraint satisfaction and spatial reasoning
- Longer puzzle sessions (30+ minutes)
- Students learning to prioritize and sequence problem-solving steps
This game develops constraint-based reasoning: identifying limitations, ranking tasks by difficulty, executing in optimal sequence, and verifying each solution preserves future solvability. These skills apply to scheduling, resource allocation, and any planning under constraints.
- Cloud progress depends on Scratch account status per source. Not all users can save across sessions.
- 81 levels is substantial. This is a long-term game, not a single-session activity.
- Source notes mention some duplicate data in level definitions. Occasional oddities possible.
- Drawing precision matters. On small screens or with limited motor control, connecting can be finicky.
- The fill-all-squares constraint on medium/hard (per source) may not be explicitly stated in-game.
- Later levels can be genuinely difficult. Permission to take breaks prevents frustration.
- No hint system. Solving strategies must develop through experience or external teaching.
Why this game is worth playing
- Our test confirmed the clear level-1 layout with visible controls and three starter pairs
- Mouse/touch drawing (from our observation) is intuitive, like pen-and-paper puzzles
- The full-fill constraint on medium/hard (per source) creates genuine spatial challenges
- 81 levels with unlockable progression (per source) provide lasting value
- Reset and erase controls (visible in our capture) support iterative problem-solving
How to play
- Click the green flag in the game frame.
- Click a number and drag a line to the matching number.
- Connect every equal pair on the board.
- On harder boards, plan routes so the whole grid can be filled.
Tips before you play
- In level 1 (our capture), identify which of the three pairs has the most constrained route before drawing.
- Solve constrained pairs before flexible pairs. This preserves options for later connections.
- On medium/hard where all squares must fill (per source), trace rough routes mentally before drawing.
- If you place a line and immediately see another pair cannot connect, erase (control visible in our test).
- Corner pairs are often constrained by board edges. Check them early in solving sequence.
- Long diagonal pairs across the board may need specific corridors before shorter pairs consume them.
- Use reset (visible in our capture) without hesitation. Fresh starts with better strategies beat continuing bad routes.
- Cloud save depends on Scratch account status (per source). Progress may not persist for all users.
Arukone Logic FAQ
How do I draw a line?
The source instructions say to click a number, then hold the mouse down while moving the pointer to draw a line to the matching number.
How many levels does Arukone include?
The Scratch instructions ask whether players can beat all 81 levels.
What is special about medium and hard levels?
The project description says all fields are covered by lines in the solution on medium and hard levels.
