Lock It Link Night Life Slot by Light & Wonder

The Lock It Feature is the entire round. Three or more red Hearts land on the same row, those Hearts get joined with a glowing border, and you get 3, 4, or 5 heart respins depending on the trigger count. So far it sounds like every other hold-and-respin bonus. The twist is what happens when fresh Hearts arrive. A new Heart adjacent to an existing border simply expands the border. But three or more new Hearts landing as their own cluster outside the border do something stranger: every single locked Heart on the board gets +1x bet ADDED to its cash value, and the respin counter resets back to its original starting number. Chain two or three clusters together and the values of the original triggering Hearts have quietly tripled while you still have a full set of spins left.

Then there's the reel-3 rule, which is doing more work than it looks. Gold Hearts randomly replace standard Hearts and each one carries a cash value plus, sometimes, a jackpot label. On reels 1, 2, 4 and 5 the only labels you can ever see are Minor (100x) or Mini (40x). Grand (5,000x) and Major (2,000x) only land on reel 3. Which means the 5,000x ceiling has exactly one path: a Gold Heart on reel 3 carrying the Grand label, sitting on a row that also triggers Lock It. Everything else is consolation cash. Fill all 15 grid positions before the spins run out and every locked symbol takes an extra +2x bet on top of whatever it had built up.

Three Bonus skyline scatters on reels 2, 3 and 4 pay 5x and then ask you to pick: Lock It, or 6 free spins on a Heart-free reel set with a Wild Multiplier scaling from 3x (no Wilds visible) up to 8x (five Wilds visible). The free games are cleaner but cap out lower than a well-chained Lock It round, so most players take the feature most of the time. Wilds in the base game also double any combo they appear in, which makes the otherwise-standard line pays from the suited Mr Lockwood, the red sports car, the champagne bucket and the leather weekend bag worth paying attention to between bonuses. Visually the whole thing sits on a navy Manhattan skyline at dusk, twin skyscraper silhouettes either side of the reels and the four-tier jackpot ladder glowing red, green, purple and blue across the top.
