Spin for a theme, or roll for difficulty.
One extra mini-ladder a day, with the parameters handed over to chance. The roulette picks a category and gives you three questions from it. The dice set the difficulty and multiply your pot by up to three — harder questions, bigger pot, and the same single mistake ending the run. Neither ever touches your PP.
Pick the wheel or the dice — one bonus game a day, one or the other.
The wheel chooses a theme; the dice choose a difficulty and a multiplier.
Play the mini-ladder and bank before you bust.
It is free, it runs in the browser, and it costs one email address.
