As a board game enthusiast, I have a long list of board games that I want to try sometime with Nucleum being on my list since Spiel last year. Today, I’m excited to finally share my thoughts on Nucleum, a game that has captured the attention of many solo players in the board gaming community. If you’re looking for a challenge that will test your strategic prowess and decision-making skills, you’re in for a treat. Let’s unravel the intricacies of Nucleum and see if it deserves a spot in your solo gaming collection.
What is Nucleum about?
Picture this: You’re the big boss of your own little industrial empire, and every move you make could either skyrocket you to success or… well, let’s just say you don’t want to mess up. That’s Nucleum in a nutshell. Where every action tile placement is a crucial step in your journey to dominance.
Nucleum isn’t just another resource management game; it’s a brain-teasing puzzle that challenges you to balance immediate gains with long-term strategy. As you consider the complexities of extending your network and maximizing your actions, you’ll find yourself completely immersed in a game where every choice matters.

How to play Nucleum
Nucleum is all about building your industrial network and outsmarting your opponents (or in my case, outsmarting this tricky AI called the Baron – more on him later).
Here’s a step-by-step guide on how to play:
Setting up the game
First things first, you’ve got to set up the game. You’ll choose your colour, grab your player board, action tiles, and markers. Then you’ll set up the main board with all sorts of tiles and bits.
You’ll place urban tiles, mines, and turbines in designated areas, shuffle those action tiles into a queue, and distribute some initial resources.
The heart of the game: action tiles
Now, here’s where it gets interesting. You’ve got these action tiles and you’ve got two choices: put them above your player board or put them on the main board. Sounds simple, but trust me, this decision will keep you up at night.
If you put a tile on your player board, you get to use both actions and maybe even reuse it later. But if you put it on the main board, you’re expanding your network.
What can you do on your turn?
On your turn, you’ve got a bunch of options:
- Urbanize: Build urban buildings in cities, enhancing your network and generating resources.
- Industrialize: Construct mines and turbines to produce essential resources like coal and energy.
- Develop: Acquire new action tiles to enhance your capabilities and strategic options.
- Contract: Fulfil contracts to earn victory points and additional resources.
- Energize: Use turbines to supply energy to urban buildings, activating their benefits.
- Subsidize: Gain additional workers or Thalers to support your operations.
Winning the game
As you play, you’ll be racking up victory points by completing objectives, fulfilling contracts, and optimizing your network. The game keeps going until the required number of end game triggers have been triggered. The player with the highest victory points at the end of the game wins.

Look and feel: the aesthetic appeal of Nucleum
Nucleum has a striking visual design that immediately captures the eye. The game board features a rich, detailed illustration of an industrial landscape, with a network of interconnected cities representing various locations for players to expand their empires. Nucleum’s colour palette is dominated by green tones, giving the game a gritty, industrial feel that perfectly matches its theme.
The action tiles, a central component of the game, are well-designed with clear iconography. This helps with gameplay, making it easier for players to quickly understand and execute their actions.
Component quality
- Tiles and boards: The game board is sturdy and well-made, able to withstand repeated plays without showing signs of wear. The action tiles, which see a lot of handling during gameplay, are made of thick, durable cardstock. This is crucial for a game that relies heavily on tile placement and manipulation. Player boards, another key component, are of good quality with clear, easy-to-read layouts.
- Tokens and markers: The various tokens and markers used in the game are typically made of solid wood or thick cardboard, adding a satisfying tactile element to the gameplay.
- Cards and rulebook: The cards used in the game, including action tiles and logic cards for solo play, are of high quality with a smooth finish. The rulebook is comprehensive and well-organized, making it easy to learn and reference during gameplay.
Overall aesthetic experience
The overall aesthetic of Nucleum really matches the theme of industrial development and resource management. The combination of detailed artwork, quality components, and thoughtful graphic design creates an immersive experience that draws you into the world of the game.
While personal preferences for game aesthetics can vary, the look and feel of the game certainly match the theme well.

How to play Nucleum solo
When you’re playing solo, you’re up against an AI opponent called the Baron. The solo mode replicates a multiplayer experience by having the Baron take actions and score points based on predefined rules and logic.
Solo setup
Setting up for solo play is pretty much the same as a two-player game, but with a few tweaks. You’ll set up the Baron’s stuff, including this deck of logic cards that basically tell the Baron what to do.
Baron’s turn
Now, on the Baron’s turn, a few things can happen:
1. It might take a “recharge turn” if it’s running low on resources or if its stopblock is at the front of the queue. During a recharge turn, the Baron gains resources and advances its milestones.
2. It might take a “railway turn” to expand its network. This involves placing action tiles on the board and resolving corresponding actions.
3. Or it’ll take a regular turn, doing actions based on its tiles.
Gameplay flow
Your turns: You play your turns normally, following the core rules of the game. You can use the Baron’s turbines to energize buildings but must pay Thalers, which convert to victory points for the Baron.
Baron’s actions: The Baron’s actions are determined by rolling a solo die and drawing logic cards. These cards indicate which actions the Baron prioritizes and how it resolves ties.
Endgame: The game ends when specific conditions are met, similar to multiplayer games. The Baron scores points based on its achievements and resources, and you compare scores to determine the winner.
Strategic considerations for solo play
- Plan your strategy in advance and try to stick to it
- Be mindful of the map becoming crowded as the game progresses
- Anticipate the Baron’s moves based on the flowchart to inform your own decisions

What I think of the game
Nucleum is definitely a game that demands attention and rewards repeated plays. After multiple sessions, I’ve developed an appreciation for its unique mechanics and strategic depth but I am not convinced that it will stay in my collection long-term.
The unique aspect of Nucleum is the decision-making process regarding action tiles. You can place them either on top of your player board or on the map, and this choice is crucial. Placing them on your player board allows you to use both actions and potentially reuse that tile. However, placing them on the map extends your network, which is essential for playing buildings and mines. This choice between two options is intriguing and adds a layer of strategic depth that I did very much enjoy.
I remember this one game where I had to choose between placing a tile for a powerful action or extending my network for a crucial mine. Opting for the latter proved to be a game-changing move, allowing me to establish a key position but at the cost of a powerful repeated action. These kinds of decisions highlight the strategic depth of Nucleum and the importance of long-term planning.
However, Nucleum isn’t without its challenges. As the game progresses, especially in two-player set ups (which you use in the solo game), the map can become quite crowded. Your decision space shrinks as the game progresses, leaving fewer spaces to place your tiles. Personally, this isn’t my favorite aspect. I prefer games where you have a bit more freedom and flexibility, even in solo play. For example, in games like Paladins of the West Kingdom, where you draw cards each turn and make choices based on the options those cards offer you. Those games strike a balance between direction and freedom that I find more fun and engaging.
In Nucleum, you need to plan your strategy beforehand, deciding what to pursue and then sticking to that plan, which adds a layer of depth but may not be the most fun if you enjoy more adaptive gameplay. While this approach has its merits and fits within the design of the game, it’s simply not my preferred style of play.
Then there’s the solo opponent. The Baron, uses a flowchart system that is relatively easy to understand. However, executing the Baron’s turns involves a series of complex decisions that can make its actions feel drawn out and kind of complicated. Personally, I don’t enjoy it when the solo opponent’s turn takes longer to play out than my own. I prefer solo games where the opponent’s actions are quick and straightforward, allowing me to focus on my own strategy.
If you’re a fan of games like Terraforming Mars or Scythe, known for their strategic depth and solo options, you’ll likely find a lot to appreciate in Nucleum. It shares similarities in resource management and strategic planning but sets itself apart with its unique action tile placement mechanic.
Overall, Nucleum offers a rich and challenging solo gaming experience that will appeal to you if you enjoy intricate decision-making and strategic planning. The game’s unique mechanics, particularly the action tile placement, provide a fresh take on resource management and network building. However, the complexity of the Baron’s turns in solo play and the increasingly constrained map as the game progresses are aspects that somewhat lessen my personal enjoyment.
In conclusion, Nucleum is a game that deserves respect for its design and strategic depth. While it may not fit perfectly with my personal preferences, I can certainly appreciate the thought and craftsmanship that went into it. For the right player, it offers a deeply satisfying and intellectually stimulating experience that will keep them coming back for more.
