The flow puzzles you've played before... were they ever actually hard? Flow Link is built for people who want real puzzles — and this update is our biggest leap yet. 【 ENIGMA MODE — difficulty beyond the limits of this genre 】 For people who truly love solving: • No hints, no solve button — not even the endpoint glow when you drag. Junk-filling is blocked too. Just you and pure logic. • Color Switchers: the two dots you connect aren't the same color anymore. • Ghost Dots: some colors show extra dots, but only two of them connect. Find the decoy. • Portals, Rotors, and boards that mix several mechanics at once. • No linear gates — pick a mechanic, start on any level you like. Beat one and you've earned the right to brag. ※ Enigma access: included with VIP and Ad-Free, or watch one ad per session. 【 FREE PICK — play whatever you feel like 】 A library of levels from every mode, organized by mechanic and board size. No unlock order. ※ Same access as Enigma mode. 【 THE MAIN JOURNEY — free, with zero interstitial ads 】 Pick the style that fits you, across 22,000+ total levels: • Kids: small boards, bright colors, fun for the whole family. • Normal: a relaxed climb through a world map of 6,000+ levels. • Time Attack: the same puzzles, half the time. • Extreme: massive two-floor boards with portals, bombs, keys and arrows — the game physically blocks junk-filling as you drag, and every level is machine-verified to have exactly one solution. No interstitial ads pop up between levels, anywhere on the journey. (Optional rewarded ads exist for bonus rewards — watching one is always your choice.) Ready to find out where you rank?
