Do you want to get more Ivory Dice in Blue Prince? This item might be one of the most important resources in the game. It lets you redraw or reroll the three room options that appear. In doing so, you'll have more flexibility when it comes to pathing toward your goal, or generating a particular room you need.
How to get more redraws and Ivory Dice in Blue Prince - Redraw guide
By default, Ivory Dice, as well as a means of redrawing rooms, tend to be fairly hard to come by, and with good reason. You're supposed to select from the rooms available to you. Sure, you might not get what you want, which is why you have to adjust to the circumstances.
Still, the more redraws you have, the more your run becomes manageable. For instance, instead of getting the Dark Room, Furnace, and the dreaded Lavatory, one reroll might net you the Hallway, Rotunda, and Vault.
Do note that the most common way of earning redraws is via the Ivory Dice in Blue Prince. Ivory Dice, similar to other items, appear randomly in the manor. They can be found in dead-end rooms, or inside chests or on desks. You just need to keep your eyes peeled. It's also worth adding that there are ways to obtain more Ivory Dice as you progress.
Boudoir

It's always a good idea to draft the Boudoir whenever it appears as an option. Not only does it have a safe that you can unlock, its default effect actually gives you +2 Ivory Dice that you can find on the dresser.
Laboratory Experiments

The Laboratory can also net you extra Ivory Dice and redraws in Blue Prince. This comes from experimentation projects:
- Effect: Choose the effect that sets your dice to +2 if the option is available.
- Cause/trigger: Pick something that you're likely to trigger often during your run. For example, if you have a Keycard or if you disabled the Keycard VAC system, you can choose: "Each time you unlock or bypass a security door."
