Cube Face Matcher: Nets and Spatial Logic

The Mission: 

Can you visualize how a flat piece of paper folds into a box? In this game, you are given a Net (an unfolded cube). Your mission is to identify which two faces would be Opposite each other (e.g., Top and Bottom) if the cube were folded up.

Math Skills:

• 3D Geometry (Nets): Understanding how 2D shapes map onto 3D objects.

• Spatial Visualization: Mentally folding objects.

• Logic: Learning rules like "faces separated by one square are usually opposites."

  
  

How to Play:

1. Rotate the View: Click and drag on the screen to rotate the paper shape in 3D space.

2. Use the Helper: Drag the Fold Preview Slider at the bottom. This visually folds the paper into a cube so you can verify your guess!

3. Select Pairs: Click on two faces that you think are Opposite Pairs.

   • Example: If you click the "Star" face, find the face that would be on the complete opposite side.

4. Complete the Set: You need to find all 3 pairs to clear the level.

   • Green = Correct Match.

   • Red = Wrong Match.

正方體對對碰：展開圖與空間邏輯

任務簡介: 

你能想像一張平面的紙如何摺成一個盒子嗎？在這個遊戲中，你會看到一個 展開圖 (Net)。你的任務是找出如果將其摺疊成正方體，哪兩個面會是 相對 的（例如：頂部和底部）。

數學技能:

• 3D 幾何 (展開圖): 理解 2D 形狀如何對應到 3D 物體。

• 空間視覺化: 在腦海中摺疊物體。

• 邏輯: 學習如「中間隔一個格子的面通常是相對的」等規則。

  
  

玩法說明:

1. 旋轉視角: 在螢幕上點擊並拖動，以在 3D 空間中旋轉紙張形狀。

2. 使用小幫手: 拖動底部的 摺疊預覽 (Fold Preview) 滑桿。這會將紙張實際摺疊成正方體，讓你驗證猜測！

3. 選擇配對: 點擊兩個你認為是 相對配對 的面。

   • 例如：如果你點擊了「星星」面，請找出位於它正對面的那個面。

4. 完成關卡: 你需要找出全部 3 組配對才能通關。

   • 綠色 = 配對正確。

   • 紅色 = 配對錯誤。
