Midas Squares — Original-Art Clone (Demo)

Midas Squares — Info

Original-art clone of the published Midas Squares concept. All symbols are original vector drawings made for this game. No Paperclip art, images, logo or text is copied.

Rules (in our own words)

7×7 grid, cluster pays. 5 or more matching symbols connected horizontally or vertically pay, anywhere on the board. Every cluster on the board pays. Bonus symbols never pay and never join a cluster.
Winning symbols explode. Symbols above fall down, new symbols drop in, and the board keeps paying until no cluster is left.
Every base spin stamps a 2×2 Golden Square on the board. Any winning cluster with at least one symbol inside the square pays the whole cluster multiplied by the square's multiplier.
After a cascade that pays a cluster touching the square, the multiplier doubles and the square grows by one row or column, on the side where most of the touching cluster's symbols lie outside it (random side if all are inside), until it covers the whole board. There is no upper limit on the multiplier except the 25,000x round cap.
King Midas's Touch: when the board rests with no winning cluster, on a spin that has not won yet or after a cascade, Midas may touch it, turning 1–2 symbols inside the Golden Square into the symbol that completes a winning cluster. That cluster always touches the square, so it pays the multiplier, then the square doubles and grows as usual. He can touch any number of times in a spin, in the base game and in free spins, but never on the Midas Spin. In our model the touch chance on a losing spin is 8% (10% in free spins).
Free spins: 3, 4, 5 or 6 Bonus symbols trigger Bonus, Super Bonus, Epic Bonus or King Midas Bonus — each 10 free spins. In free spins the Golden Square is stamped once and is persistent for the whole bonus: it keeps its position, growth and doublings and never resets. It starts at x2 (x64 in King Midas Bonus). Starting size: Bonus 2×2, Super 3×3, Epic 4×4, King Midas 4×4. During free spins every Bonus symbol that lands awards +1 free spin.
Midas Spin: one spin with a 4×4 Golden Square starting at x128. No Midas Touch on it.
Max win 25,000x bet per round. The round ends immediately at the cap.

Volatility

Level	Win	Profit	Any bonus	Bonus	Super	Epic	King	100x+	Max win
Normal	1 in 5.1	6.3%	1 in 222	1 in 305	1 in 1k	1 in 4k	1 in 216k	1 in 553	1 in 2M
Other levels use the same published table shape; our calibrated equivalents are: Very Low p_win 0.16 / square-touch 0.18, Low 0.14 / 0.20, Normal 0.12 / 0.22, High 0.10 / 0.26, Extreme 0.08 / 0.30, with cluster sizes shifted smaller at low volatility and larger at high. All levels target the same 96.70% RTP in theory; higher levels win less often and pay bigger when they do.

Ante & Buy prices (at $1 bet — all prices scale with bet)

Option	Cost	What it does
Ante	$3 / spin	Bonus trigger any 1 in 74 (Bonus 1/102, Super 1/339, Epic 1/1300, King 1/74000)
Super Ante	$6 / spin	Any bonus 1 in 44 (Super 1/59, Epic 1/178, King 1/20000; no regular Bonus tier)
Epic Ante	$20 / spin	Any bonus 1 in 41 (Epic 1/43, King 1/857)
Super Bonus buy	$300	Starts a Super-tier 10-spin bonus immediately
Midas Spin	$1,000	One spin, 4×4 square at x128, no Midas Touch
Mystery Bonus	$500	No feature 49%, Super 40%, Epic 10%, King Midas 1%. If it rolls No feature, the cost is lost and no spins play.

Honest note on Ante and Buy prices: the prices and trigger rates above are the published ones. In our calibrated model a free-spins trigger averages about 30–33x bet, so a $300 Super Bonus buy and the Ante costs are not RTP-matched to 96.70% in our model — they cost far more than the model's average bonus value. Buy them knowing that; the base game at the normal bet is the part calibrated to the 96.70% target.

Math — our calibrated model

Paperclip's exact symbol weights and board-generation code are not published, so this is a calibrated equivalent model built to the published paytable, features and 96.70% RTP target — not Paperclip's server code. The board you see is built to realise the model's outcome: the winning cluster's symbol, size and square-touch are decided by the provably-fair draw first, then the board is laid out so that cluster pays exactly what the model decided, with no accidental extra clusters.

Base (Normal): p_win (initial cluster) 0.12 · Golden Square touch 0.22 · cascade win 0.15 per cascade, decreasing x0.6 each further cascade; cascade clusters are size 5 only · Midas Touch 0.08 on a losing spin (0.10 in free spins) · Golden Square starts at x8 fixed in the base game.
Symbol weights: fruit 0.06, rose 0.09, goblet 0.13, blue 0.18, green 0.18, purple 0.18, heart 0.18.
Cluster size distribution: 5: 42%, 6: 24%, 7: 12%, 8: 8%, 9: 5%, 10: 4%, 11: 2%, 12: 1.5%, 13: 0.8%, 14: 0.4%, 15+: 0.3%.
Free spins: win prob 0.24 per spin, touch starts 0.45 (Super 0.55, Epic/King 0.65), cascade 0.18, square multiplier doubles per winning free spin (persistent doubling, in addition to cascade doubling inside a spin), touch +0.03 per winning spin up to 0.90, +1 spin per bonus symbol at 10% per spin in the model (in the game, the board shows a bonus symbol when the model awards the extra spin).
Golden Square start multiplier: the demo report mentioned x8/x16/x32, but a random x8/x16/x32 start with our paytable simulates at 213% RTP, so we fix the start at x8 to hit the 96.70% target. That change is disclosed here, not hidden.
Simulation (verify_final.py, 200,000 spins × 3 seeds): total RTP 94.8% / 96.0% / 96.2%, base 80.9–82.2%, free spins 13.8–15.0%, win rate 18.8–19.1% (1 in 5.25–5.32), trigger 1 in 214–237, free-spins average ~30–33x bet per trigger. Target 96.70%.
Midas Spin in our model: single spin, 4×4 square at x128, square-touch 0.65, no Midas Touch. It is a high-variance single spin and is not calibrated to 96.70% on its own.
Midas Touch clusters in our model are drawn from the same size distribution; the board shows the touch completing the cluster with 1–2 symbols inside the square (3 in the rare 15+ case, to keep the pre-touch board losing).
