就是任何一个角，看见1个角两个面的颜色，能推出第三个面的颜色。正常左手持魔方，其中，BFL，UFR，DFR三个角就是只能看到两面的，如果你能快速反应出第三个面的颜色，无疑，对你加快做F2L有极大的帮助。

How to PlayLook at the two corner stickers to identify the corner and then click on the corner in the exploded cube below. If you're not used to the default orientation of the cube, click on the arrows to turn the cube to your desired orientation. Keyboard controls may also be used to improve speed.
看到一个角的两个面，算出第三个面的颜色，点击下面对应的角块。如果你不是用国际配色魔方，点击箭头，转换对应面的颜色。也可以用键盘快捷鍵来回答。
If you're not interested in identifying pieces in which U stickers are visible then check the 'NOU' option. This is useful if you're training for F2L lookahead only.
如果你对顶层的U面色块不感兴趣，可以点击"NOU"选项，这对你预判F2L很有帮助。
If you're just starting out, it may be useful to concentrate on one corner location at a time. Use the checkboxes marked L, R, and D to control which corners are shown.
如果你已开始，某个时刻只用注意一个角块。用标有L、R、D的选择框，来控制显示哪个角。
