According to NewAir [1]https://www.newair.com/blogs/learn/how-long-for-ice-cubes-to-freeze, ice made in a standard ice tray — those plastic models with space for a dozen tapered cubes — takes about three to four hours to freeze in your home freezer. Water freezes when it reaches 32 degrees Fahrenheit (0 degree Celsius[2]https://calcpark.com/temperature-converter), but the time it takes to do so depends on several factors that may be different in your freezer than in your neighbour’s.
It is interesting to note that hot water can in fact freeze faster than cold water for a wide range of experimental conditions. This phenomenon is extremely counterintuitive, and surprising even to most scientists, but it is in fact real. The phenomenon that hot water may freeze faster than cold is often called the Mpemba effect.

The Mpemba effect is named after Tanzanian schoolboy Erasto Bartholomeo Mpemba (born 1950) whose story of it in 1963 became highly popularized. The schoolboy’s findings have never been replicated under controlled conditions. The discovery and noted observations of it however originate in ancient times, having been common knowledge according to Aristotle during his time. [4]https://en.wikipedia.org/wiki/Mpemba_effect
So you can make ice cube faster by using hot water instead of cold water.
