A chart, not a counter
The multiplier is drawn as a market line that swings on its way up, so a round reads like a price moving — and cashing out reads like selling.
Index
Play the market. Discipline beats luck.
Index is a shared-round crash game drawn as a market. A betting window opens, the market line climbs, and the multiplier rises with it until the player cashes out or the market crashes. Two bet slots run side by side, each with its own auto bet and auto cash-out, and the whole table is trading the same round.
About the game
Sell before the crash
Index takes the oldest question in crash — take it now, or wait for more — and asks it in the language of a trading floor. The multiplier is the market, the line on the chart is its price, and cashing out is selling. Every player in the room holds a position in the same round, so the crash lands on everyone at once.
The climb is continuous: the multiplier is e raised to 0.14 times the seconds elapsed, held between 1.01× and 300×. The line is not drawn straight. Each round deals one of a library of market trajectories, so the price swings and dips on its way up the way a chart does, while the multiplier underneath it rises exactly as the curve says.
Where a round crashes is fixed before it starts, from a seeded HMAC-SHA256 draw, and every crash point can be checked from its revealed seed once the round is over. A small share of rounds crash on the open — that is where the configured edge sits.
Index runs on the platform like the rest of the catalogue: one wallet, one launch, and the same integration an operator already has for Crashbook, Slotbook and Yachter. The figures below are the configuration it runs on.

Features
What Index brings to a lobby
What the title gives a lobby, and what it asks of the platform behind it.
Two positions, two nerves
Two bet panels side by side, each with auto bet and auto cash-out, so a player can take profit on one early and let the other ride.
A city at night
The market climbs over a skyline after dark, in gold and blue — a trading-floor mood rather than a casino one.
Crash points you can check
Each round's crash point is committed before it starts and can be re-derived from its revealed seed once it ends.
Built for one hand
The chart, the bet panels and the last results are laid out for a phone held upright first, and open out from there.
Seamless wallet, one integration
Index launches through the same wallet as the rest of the catalogue, so an operator already integrated for one title has it too.
