Are programs to unscramble words available in Spanish?

Find programs to unscramble word puzzles using a Spanish dictionary on sites such as Vocabula.com, HughCalc.com and A2ZWordFinder.com, as of 2015. Each site allows the user to enter in a series of letters and receive a list of all possible word combinations that use those letters.

Vocabula.com offers a spartan Spanish word puzzle solver which only features a single letter entry field and processing button, though it allows the user to choose from a short list of other language options. The site launches a separate window to display word results. The tool on HughCalc.com displays results on the same page, but does not support characters with special symbols.
