Det kan være yderst svært for en ambitiøs udvikler at skabe opmærksomhed omkring ens spil, men én har valgt en ganske bizar måde at gøre det på, der dog lader til at virke. Spillet hedder 99 Floors, og ideen er at spillet er så svært, at skaberen bag er villig til at give dig $5000 hvis du skulle besejre det.
Luke Powell, der har skabt 99 Floors, siger på spillets hjemmeside, siger at ideen kom efter at han måtte sande at han ikke fandt andre svære spil... svære nok.
"The idea for the game came from wanting to develop a roguelite so endless and difficult that it would be "frustratingly addictive" for the player who wished to complete it. The game did better than expected following it's release for a game with no marketing budget or prior following. Several people began to share their attempts to beat the game. Game sales equaled a few hundred within the first week. This unexpected, better-than-predicted sales paired with no one even coming close to the game lead me to the idea of setting up a cash pool (roughly a third of all sales at the time) for the first person who could successfully beat the game. As sales increased, so did the cash pool."
Spillet blev udgivet d. 4 august, og der er stadig ingen der har besejret det.
