CRY FOUL!!!!

I don’t understand how some words are acceptable in WORD WIPE, but those same words are NOT accepted in SPELLBOUND. Also noticed that some perfectly correctly words are not accepted at all. I taught science for 15 years and biomes was a yearly taught area. However, SPELLBOUND won’t take it, as well as other words. Both games are made by Arcadium so someone needs to report this to the company. UNFAIR!!!
