The best way to learn Regular Expressions is to play with combinations. Our game introduces the parts, then challenges your ability to put them together. In Expressions, you'll solve a series of sorting puzzles, using real regular expressions to sort lines of text (strings)...
Finitris is a game where the objective is to construct a finite state machine given a regular expression. This is done by placing states on the game field, and labeling the connecting arrows with particular characters.
Need to test a deterministic finite automaton for an upcoming course assignment, or just curious? Then you've come to the right place! DFA Tester is a simple and intuitive application to build and test deterministic finite automatons.
