Three casino concepts, each a working prototype in the browser. Open one and play a round, then read what the mechanic is doing and what it costs in RTP.

01 · Crash game Best work

Shuriken Tower

Two ninja climb a tower. Cash out before a shuriken takes your climber off the wall.

RTP97%
Climbers2
RoundSeeded

In most crash games the multiplier is a number printed over the artwork, and the artwork could be anything. Here the number is the game: how high your ninja gets is what you are paid, so you read the round by watching the wall rather than a dial.

Two climbers run every round, one bet each, which makes a round a race you are inside of rather than a line you are waiting on.

Why it is worth a lookIt gives a crash game something crash games usually lack: a reason to watch. The tension lives in the world, and the player always knows how close they are to losing it.

The detail

What the player does. Place a bet on either climber, watch the altitude, and cash out before the shuriken lands. Both climbers are independent, so you can back one or both.

Why the maths holds. RTP is 97.00% and stays flat across every cash out point, so there is no height that quietly pays worse than another. The round is fixed by its seed before it starts.

02 · Slot feature Best work

El Dinamito

Cluster wins fill the Fuse Meter. A full meter detonates every marked Charge at once.

RTP96.3%
Volatility3/5
Max win12,500x

A bonus that fires at random feels like weather. The Fuse Meter replaces the trigger symbol entirely: every cluster win fills one bar, and nothing is waiting on a scatter landing in the right place.

So the player watches a bonus being built, one win at a time, instead of being surprised by one. The feature is readable from the first spin, which is the part a new player usually misses.

Why it is worth a lookIt is a presentation layer, not a new maths model. The RTP, the volatility and the max win are all untouched, so a studio can put it on top of a model that already passed certification.

The detail

What changes. The trigger symbol goes away. Cluster wins fill the meter; a full meter detonates every marked Charge simultaneously.

What does not change. 96.3% RTP, 3/5 volatility and a 12,500x max win, all as the base game had them. The feature redistributes attention, not money.

03 · Step and cash out

Wolfhunt

A field of twenty five patches. The wolf keeps moving until you cash out, and every patch it clears pays more.

RTP98%
Empty patches1 to 10
Multiplier0.98 ÷ odds

A few of the twenty five patches are empty. The multiplier is not a tuned table: it is 0.98 divided by the chance of having survived that far, so the price of nerve is the honest one.

The number of empty patches is a dial, not a constant. Pick the range and you have picked the game's whole risk curve, which makes the same build serve a cautious player and a reckless one.

Why it is worth a lookThe simplest of the three to put in front of a player, and the easiest to retune: one parameter moves it from gentle to brutal.

The detail

The multiplier rule. 0.98 divided by the odds of surviving to that patch, so every step is priced at what it actually costs.
