Frame Chains

A slot multiplier mechanic layered over a classic 5×3, 20-line video slot. Every symbol sits in a frame that draws fresh marks on each spin. Marks on facing edges connect, linking frames into chains — and a chain that reaches an anchor socket on the window edge lights up and multiplies every line win it crosses by its size. The reels decide what you win; the chains decide how big.

How to Play

Set your bet with TOTAL BET (all 20 lines are always active) and tap SPIN. As each reel lands, its frames materialize and their connections fuse. Chains glow dim until they connect into one of the anchor sockets on the window edge — in the base game, the three sockets on the left. A lit chain multiplies every line win it crosses: a win crossing a lit 4-chain pays ×4, shown by the badge on the winning line. Scatter pays are never multiplied.

Scatters start the free games, where the frames run richer (every frame carries at least one mark) and all 16 sockets around the window are active, so chains light from the left, right, top, and bottom. The hardware changes color to show the bonus is live.

Two Versions, One Mechanic

The VERSION selector in the lower-left console demonstrates the two ways the mechanic can ship. In Version 1, the frame feature is integrated into the game math: frames draw on every spin at the regular bet, and the pay model is designed around them from the start.

In Version 2, the frame feature is a paid feature over an unmodified base game. The FEATURE BET button toggles it: off, you are playing the underlying video slot as-is at the regular bet; on, the total bet doubles and the extra wager activates the frames — chains multiply your line wins, and the free games trade their pay multiplier for the richer frame set. The underlying math never changes; the player bets extra to activate the feature. Built this way, the mechanic can be layered onto essentially any video slot with only minor modifications.

The Force button auditions specific results on demand: Free spins takes you straight into the bonus round, Big chain shows a five-cell chain multiplying a top line win ×5, No chains shows the same win paying as printed, and Jackpot lands the five-wild top award. The demo runs entirely in your browser on the OG Game Engine — no downloads or plugins.
