 You should call your `detectFullHouse` function when your `rollDiceBtn` is clicked.
 
 ```js
-const counts = (arr) => arr.reduce((counts, num) => {counts[num] = ++counts[num] || 1; return counts}, {});
-const isFullHouse = (arr) => arr.includes(3) && arr.includes(2) && arr.length === 2;
-// Absurdly high, but will either timeout or bail early when assertion runs.
-for (let i = 0; i < 100_000; i++) {
-  rolls = 0;
+// Temporarily modifies Math.random to guarantee full house.
