Classic: connect matching colored endpoints without crossing, and fill every cell. Exact+: each color also has a length budget. The path (including both ends) must equal that number, plus every +K / −K tile the path visits.
Puzzles themselves run on your device. You need a network connection for ads (AdMob) and for App Store / Google Play purchases. There is no ExactLink game server to log into.
Progress is stored only on that device. Uninstalling the app or clearing its data deletes it. We cannot restore puzzles from our side. Non-consumable purchases (Extra Packs, Daily Quest, Remove Ads Pack) can be recovered with Restore Purchases in the shop, using the same store account.
You start with a few hints. You can buy hint packs, watch a rewarded ad, or use hints included in the Remove Ads Pack. Banner and interstitial ads appear in the free version until ads are removed.
Each board size has 10 Daily Quest puzzles for the local calendar day; levels 1–2 are free. Extra Packs add 250 more levels per size (6×6–10×10). The Remove Ads Pack also unlocks Extra Packs and Daily Quest.
Purchases are handled by Apple and Google. Refund requests must go through the App Store or Google Play, not through us.
Email us with your device model, iOS/Android version, and a screenshot if you can. Please mention whether you were in Classic, Exact+, or Daily Quest.
Classic：連接同色端點、線唔好交叉，並填滿整盤。 Exact+：每種顏色另有長度預算。路徑（含兩端）必須等於該數字，再加上路徑經過的每塊 +K / −K。
謎題本身在裝置上運行。廣告（AdMob）以及 App Store／Google Play 購買需要網絡。沒有 ExactLink 遊戲伺服器要登入。
進度只存在該部裝置。解除安裝或清除資料就會刪除，我們無法從伺服器還原。非消耗型購買（Extra Packs、Daily Quest、Remove Ads Pack）可用同一個商店帳號，在商店頁撳 Restore Purchases 救回。
一開始會有少量提示。之後可以買提示包、看獎勵廣告，或使用 Remove Ads Pack 附帶的提示。免費版會有橫幅與插頁廣告，直到移除廣告為止。
每個棋盤尺寸每日有 10 題 Daily Quest（依裝置當地日期）；第 1–2 題免費。Extra Packs 為每種尺寸另加 250 題（6×6–10×10）。Remove Ads Pack 亦會解鎖 Extra Packs 與 Daily Quest。
付款由 Apple 與 Google 處理，退款要經 App Store 或 Google Play 申請，我們處理不到。
