To Be Sold
To Sell
intransitive verb, ichidan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means sell, so the verb version is to sell or to be sold.
うれる
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You learned this reading already, so you should be able to read it! It's the same reading as 売る where you're trying to sell some Uni (う)!

This game will definitely sell well.
