Fruit Lock 7 Slot by Fazi

Most of the time the reels behave like any old fruit machine, then the Full Reel Feature fires without warning and the whole screen reorganizes itself. It picks somewhere between 2 and all 5 reels at random, then floods each chosen reel with a single repeated symbol, stacked top to bottom. Every locked reel shows the same symbol, so when four or five of them sync up you are staring at a near full-screen match. That is where the 3,000x ceiling comes from. Any symbol can get pulled into the lock except the red star Scatter, which keeps doing its own thing.

The naming is a little mischievous. "Lock" suggests a hold-and-win or coin collector, and there isn't one here, no respins, no free spins, no buy button to force the feature. It triggers when it triggers, purely random, on the base bet. So the rhythm is long stretches of ordinary spins punctuated by the occasional reel sync, which is exactly the kind of pacing you'd expect from a classic build dialed up to a high-variance temperament.

The paytable rewards the obvious icons. That faceted red 7 is the top fruit-rank payer, the golden bells sit just under it, and the cherries, lemons and oranges fill out the floor. The red "W" Wild is unusual in that it both substitutes everything (Scatter aside) and ranks as the single best symbol on the board, five of them paying 150x. The Scatter pays from anywhere on screen up to 500x and gets added straight onto your line wins rather than launching a bonus.

Three mystery progressives ride along the top, labeled Gold, Diamond and Platinum, each fed a slice of every bet and dropped at a random hidden threshold, with bigger stakes improving your odds. Land a win and you can run it through the red-or-black Gamble ladder, doubling each correct guess up to a 50,000 cap. Visually it is all warm golds and reds, twin cherries and sliced watermelons glossed up against a rayed amber backdrop, and the logo leans into the gimmick with a little gold padlock standing in for the "7".
