目標
左右兩張圖幾乎一樣，但右圖有幾處不同。在時間內把它們全部找出來！
不同的種類
- 東西不見了，或多了一樣東西
- 顏色變了、大小變了
- 左右翻轉、位置稍微移動
操作
- 在左圖或右圖點不同的地方，答對會在兩張圖上圈起來
- 點錯扣 3 秒，圖片會晃一下
- 「提示」直接圈出一處，每關最多 3 次，每次扣 5 秒
- 鍵盤：Tab 選到圖片後，方向鍵移動準星（Shift 加速），Enter 或空白鍵點選
- 「重來」只清除圈記，時間照走、不計完美與速度成就；時間到後「再試一次」會重新計時，但同樣不計這兩項成就
難度與關卡
- 簡單 5 處 / 90 秒、普通 7 處 / 105 秒、困難 9 處 / 120 秒
- 過關後進入下一關；時間到可以重試同一關
- 「每日」是當天所有人相同的題目（普通難度）
Goal
The two pictures look the same, but the right one has a few differences. Find them all before time runs out!
Kinds of differences
- Something is missing, or something was added
- A colour or size changed
- Something is mirrored or moved slightly
Controls
- Tap a difference on either picture; a correct tap circles it on both
- A wrong tap costs 3 seconds and shakes the picture
- Hint circles one difference for you, up to 3 per level, 5 seconds each
- Keyboard: Tab to a picture, arrow keys move the crosshair (Shift = faster), Enter or Space taps
- Restart only clears the circles; the clock keeps running and perfect / speed awards no longer count. Try Again after a time-out restarts the clock, but those awards don't count either
Difficulty & levels
- Easy 5 spots / 90 s, Normal 7 spots / 105 s, Hard 9 spots / 120 s
- Clear a level to move on; if time runs out you can retry the same level
- Daily is the same puzzle for everyone today (Normal difficulty)
