Griddle Fun

A game on a live crypto chart: you tap the grid cell you think the price will hit, and win at that cell’s multiplier. The hard part was the maths of pricing every cell. I did it together with a mathematician: I set the task, tested his results and sent back what was off, while also building the game itself. The simulation testing was mine — bots playing different strategies, greedy and otherwise, against the payouts — until the odds held up. A run over 604,800 seconds of prices (one week) came out almost exactly at break-even, ROI about 0.4%, as designed.
