從一個點按住拖曳,沿著線把每條線都畫過一次;也可以依序點擊相鄰的點。點可以重複經過,線不行。
從一個點按住拖曳,沿著線把每條線都畫過一次;也可以依序點擊相鄰的點。點可以重複經過,線不行。
用一筆把圖上所有線段各畫過剛好一次。點可以經過很多次,但同一條線不能畫兩次。
數一數每個點連了幾條線:如果有兩個點連了奇數條線,就一定要從其中一個開始、在另一個結束;如果全部都是偶數,從哪裡開始都可以,最後會回到起點。前 20 關會在可用的起點上輕輕閃爍提示。
前 10 關是手工圖形(房子、星星、信封…),之後由種子產生,越後面越大,每一關都保證有解。「今日挑戰」每天一題,所有人相同。
快捷鍵:U / Backspace = 悔一步,R = 重來,N = 下一關,P = 暫停。
Trace every line exactly once in a single stroke. You may pass through a dot many times, but never draw the same line twice.
Count the lines at each dot. If two dots have an odd count, you must start at one of them and finish at the other. If every count is even, start anywhere and you will end where you began. Levels 1 to 20 gently pulse the valid start dots.
Levels 1 to 10 are hand-made shapes (house, star, envelope...). After that they are generated from a seed and grow larger, and every one is guaranteed solvable. The Daily puzzle is the same for everyone each day.
Keys: U / Backspace = Undo, R = Restart, N = Next level, P = Pause.
