I love this game, we play on PS4 and hook our phones up, but damn, the bugs are atrocious. Kicks you off the phone app several times in a single round, which means you miss your turn and lose the game. Happens to both me and my girl using samsung s21 and s22 phones. Its a great game, im really surprised how many bugs there are on it, because otherwise the game is awesome.
Sony, this is still a very relevant game. Works on both PS5 and PS4 but the app itself has not been updated for 2 years. As others below, I get kicked out (and so do most of my frieds) randomly about 4-8 times every game. This makes it impossible to compete. I think the app is fine but it needs some further bug fixes. I also have a pixel 6 pro and I never get kicked from that device. But my daily driver is a Galaxy S22u and this is terrible. My avatar pic is a black spot. Camera sees nothing.
Fun overall, but completely unbalanced final round for 5-6 players. You can outscore every other player prior to the finale by 10,000 points, which means nothing during the ascent of the final pyramid. If you go in being first and are a strong player, other players can prevent you from having any chance of winning. You'll move up 2-3 levels, while other players scale the pyramid easily for the win. A game where the points don't matter! Don't bother scoring. Just play the final round for the W.
