I use this in my first grade classroom when teaching our silent letter digraphs--- ck, ph, gn, wr, and kn.
The words listed on the board vary in difficulty and other essential phonetic skills including: blends, other two-letter digraphs, pig-pens, short and long vowels sounds, silent e, adjacent vowels, bossy R, and some of the 5 rules of Y.
It can be played in either a literacy center or a small group setting. I suggest no more than 4 players, but this could vary in your own classroom. The only other items needed would be a single dice (1-6) game pieces (1 per player).
