My BGG Comment

2019: KS, Played at SPIEL '19, enjoyed the tile laying, bonus scoring and the little rovers quite a bit. Good game for SF fans who look for a quick polyomino style game. Rating: 9 2026: My favorite boardgame tetris. And it still holds true. The combination of polyominoes and tracks leading to nice combos is just perfect. (It's not a "quick" game as I stated above, it is not slow but bigger than most polyominoes games I have played). The only thing I dislike about this game is the lid lift caused by the lid for the lazy susan. Oh well... I really enjoy this solo but it has been a frequent "We need something not-a-party-game for 6 players" solution. It is one of my biggest crowdfunding successes in so far as I really like the game. I have backed a large number of campaigns and few of those games have become staples in my collection. This is one of them. Rating: 9

    My favorite boardgame tetris. And it still holds true. The combination of polyominoes and tracks leading to nice combos is just perfect. The only thing I dislike about this game is the lid lift caused by the lid for the lazy susan. Oh well... I really enjoy this solo but it has been a frequent "We need something not-a-party-game for 6 players" solution. It is one of my biggest crowdfunding successes in so far as I really like the game. I have backed a large number of campaigns and few of those games have become staples in my collection. This is one of them. * Player Count: 1 * My current rating: * Total Lifetime Plays: 36 (I saw my rating of 9 and mistook it for playcount and thought that had to be very wrong and it is) * Rules Retention: Good. It is also an easy teach at least to people who have played a few boardgames. I once had a newbie play this and had to coach her through the whole game. (I have some small issues with the solo mode and the event deck) * Keeper: Definitely. I love it at all player counts. * Recommended: For anyone who likes somewhat involved polyominoes games and doesn't want to go as far as A Feast for Odin 😉 Also well done simple tracks with good combo bonus potential. * Competition: Patchwork (light polyominoes), A Feast for Odin (heavy polyominoes), 7 Wonders (synchronous play)

    Move up the tracks as you transform your planet into the perfect polyominoes layout of your dreams (those are dreams, not nightmares!). There is the lovely rotating susan that deals you just the worst tiles for your planet… deal with it. There are asteroids incoming… quick move your rover to collect them all. Why it is cozy? * Parallel play is great to keep playtime down * Interaction is through the tile drafting / lazy susan and the competing goals but mostly non-existent * It is easy to teach * Tile laying is cozy * The combos from the tracks are quite satisfying * It is the cozy game you want to get out if you have 6 people and don‘t want to be there for dinner still.

    My favorite Polyominoes game since I playtested it at SPIEL years ago. The solo is fun and the variability an additional bonus when the basic puzzle could keep me occupied for ages. Ranking Last year: 6 (🔻3 )

    My tetris biggie. I really don't know why I need other tetris games. This one does it all. The actual tiles fit together nicely in a very classic polyominoes game and the combo-y tracks carry it into "again again again" territory. Even though in a year where I played a lot fewer games than in other years I only played 2 games. Solo Plays 2025: 2 Rank last year: 9

    My favorite polyominoes game. It is just so good. The combination with tracks as the second mechanism works so well. I lose the solo a lot. But that doesn‘t matter because even losing it is fun to try my best and cover the planet with tetris. And the variability of planets and corporations means there is always something new to try. It‘s also been a hit with multiplayer especially because it plays up to 6 in a decent amount of time. Solo Plays 2024: 14 Ranking last year: 9

    #6 I mentioned I love polyominoes games. This is the polyominoes game to rule them all. By far my favorite of all of these. It has huge variability and very satisfying combos with the different tracks you move up on depending on which territory you placed this round. This is also the game that proves that tracks can be fun. This is a solo puzzle, no bot needed. But in the solo you have to play with events to keep things interesting and get your target score. It is a bit expensive for „just a polyominoes“ game but then, you won‘t need another one. I have played it multiplayer and the Lazy Susan that gives each player just 2 tiles to chose from each turn really works wonders to bring that together, too. But mostly I play this solo and still haven‘t managed to try all planets and corporations. Very satisfying, highly recommend if you like fitting tetris tiles on a map.
