Secret City Gold turns geometry into a post-win modifier. Its 5 x 4 board first pays across 25 fixed lines; a random shape can then convert every enclosed position into one matching symbol. In free spins, those patterns also extend the round while wins build a multiplier. Three scatters provide entry to that free-spin sequence.

The result before the shape appears
The base calculation uses twenty-five fixed paylines. Ordinary symbols form the initial result before the pattern feature intervenes, preserving a clear order: line wins are settled first, then the selected area may be transformed.
A random geometric pattern encloses part of the board and changes those cells to one symbol already found inside the shape. The conversion can create a larger matching arrangement, but its value depends on the chosen area, the source symbol and whether the new arrangement satisfies a payline.
Patterns buy time as wins add value
Three scatters start free spins. Every pattern produced during the round adds one extra spin, so the spatial modifier doubles as a duration mechanic. A pattern can therefore be useful even before its converted symbols are evaluated.
Each bonus win raises a running multiplier by 1x. Pattern creation, extension and multiplier growth remain separate steps: the shape adds time, its conversion may make a win, and only a completed win advances the factor. That chain is powerful when connected but never automatic.
A volatile 10,000x framework
The referenced version records 96.06% RTP, high volatility and a maximum win of 10,000x. It was released on 16 January 2023. Those numbers identify the captured standard game, while an operator may offer another approved setup that should be checked in the help panel.
Random shape and timing create the practical uncertainty. An enclosed area can contain an unhelpful mix, and a converted board still needs a valid winning combination. Even when a pattern grants an extra spin, the multiplier remains unchanged unless a win follows.
Strengths
Patterns have a visible, bounded effect on the grid.,Every bonus pattern adds a spin.,Winning feature results increase the persistent multiplier.
Weaknesses
Pattern shape and placement are random.,A conversion may not create a useful line win.,High volatility can leave the progression underdeveloped.
Our Editor’s View
Secret City Gold links board transformation, added time and win-based value without collapsing them into one guaranteed reward. That separation makes each pattern easy to audit and gives successful chains a clear cause. It also explains the main limitation: an extra spin is certain when the pattern appears, but useful conversion and multiplier growth are conditional. The result is a readable yet distinctly volatile feature loop. Its geometry is more than presentation: the outline determines exactly which positions change and which remain untouched. Following that boundary is the clearest way to judge whether a pattern has genuinely improved the board.
