What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Rules: Play cards that add up to multiples of 10, using up to 5 cards at a time. Base score for a hand = {Hand Size}^2 (i.e. 2 card hand = 4 points, 3c = 9, 4c = 16, and 5c = 25) +1 bonus score for each card that is a duplicate of another card in the hand. (e.g. 6+6+6+6+6, or 2+2+2+7+7 will each score 5 bonus points, and 5+5 would score 2.) Add 1 second for the clock for each multiple of 10 the scored hand is. (i.e. 1 second for a hand that adds to 10, 2 for 20, etc.) Spend 2 points to draw an additional card. Pros: ++ It's free. Free is free. + There are three music tracks so at least there's SOME variation to be found despite the unchanging gameplay. (Would be nice if there was an option to have the music keep playing while the window wasn't in focus.) Cons: - Would appreciate hotkeys for Start and Reset on top of the ones for Draw and Give. Even just a default expectation of Enter to start a game would be nice. - The rules are only available in Korean despite them being really straightforward. Seems like virtually no work to implement, so it's a shame not to see even a basic translation of the rules. ---- The entire summary is just AI hallucinating a game that bears no resembl…2 found this helpful

"SUM" is a very curious entry here on Steam because the sales page is sheer rubbish... it's like the developer asked a chatbot to create a store sales blurb without actually explaining what game it's for. This is NOT a platformer, or anything else that the store blurb describes. Instead, this is a minimalist browser/mobile tier "card matching" game that kind of works like the Pazaak minigame from Star Wars: Knights of the Old Republic, and if you don't know what KOTOR is, then drop what you're doing and guy buy it here on Steam, because while it's old, it's awesome, and without KOTOR there would be no Mass Effect either. Anyway, enough about actually good games, let's talk about this junk. There's no English translation for the game, but that's okay. The language of bad games is universal. While I couldn't find this on the mobile app stores, everything about it looks and feels like it's a mobile app designed for mobile phones... for PC gaming enthusiasts, it's not going to give you a cutting edge PC gaming experience. That alone is enough to disqualify this from any recommendation. We don't spend thousands building gaming rigs so that we can pretend they're iPhones and pla…
This game lies to u by its images there's no sound option there's no question mark box there's not the scoreboard, time nor reset button. U put numbers to get 10s and btw yes if the time runs out ur stuck then because there's no option to reset unless u close and reopen the game. I heard from a review that there's 3 songs I can't confirm that I only heard one. also like why is English not supported if that's literally the only language the game is in. Only good thing is it's free and u can play it once property
