Put Your Skills to the Test with These Solo Challenges
Buy The Under Falling Skies Board Game
Under Falling Skies
Under Falling Skies is a pure solo defence puzzle where alien ships descend toward your city while you juggle research, energy, and anti-air defences. Each round you assign dice to actions, but higher values make the enemies drop faster, turning every placement into a risk-rewarding calculation. The multi-mission campaign and variable cities keep the challenge fresh, and success feels properly earned rather than lucky.
Average Playtime: 20-40 minutes

Number of Players: 1
Difficulty (BGG Weight): 2.40/5
Sherlock Holmes: Consulting Detective
A pure deduction classic, Sherlock Holmes: Consulting Detective turns you into an investigator scouring Victorian London for answers. Each case drops you into an open world of newspapers, directories, suspects, and cryptic leads, and it’s up to you to piece the whole puzzle together. There are no dice, no randomness, and no luck, just your own logic and attention to detail.
Average Playtime: 60-120 minutes

Number of Players: 1-8
Difficulty (BGG Weight): 2.66/5
Friday
Designed specifically for solo play, Friday casts you as Friday, trying to help Robinson Crusoe survive the island and eventually fend off pirates. You’ll gradually improve a terrible starting deck into something efficient enough to survive increasingly dangerous hazards. The difficulty ramps up quickly, but losses teach you how to refine your deck and prioritise cards. It’s small, portable, and surprisingly punishing for such a simple ruleset.
Average Playtime: 25 minutes
Recommended Age: 13+
Number of Players: 1
Difficulty (BGG Weight): 2.15/5
Sprawlopolis
Don’t let the tiny deck fool you, Sprawlopolis is a serious solo (or co-op) brain burner. With just 18 cards, you’ll build a city that needs to satisfy three variable scoring conditions, plus keep road length under control. Every card placement affects multiple goals at once, forcing you to weigh short-term gains against long-term efficiency. The quick playtime makes it easy to reset, but hitting the target scores can be genuinely tough, which makes it so addictive.
Average Playtime: 15-20 minutes
Recommended Age: 8+
Number of Players: 1-4
Difficulty (BGG Weight): 1.80/5

Buy The MicroMacro Crime City Board Game
MicroMacro: Crime City
MicroMacro: Crime City turns the whole table into one giant puzzle: a sprawling, detailed city map filled with tiny crimes and clues. On your own, it becomes a pure investigation challenge as you follow trails, track suspects, and piece together what happened across different locations and times. Some cases are straightforward, while others require real lateral thinking and careful observation.
Average Playtime: 15-45 minutes
Recommended Age: 12+
Number of Players: 1-4
Difficulty (BGG Weight): 1.10/5
Hostage Negotiator
In Hostage Negotiator, you’re a lone professional trying to talk down abductors and save lives using a card-driven system that’s far harsher than it looks. Every conversation card you play can calm the situation, escalate it, or spiral into disaster, with dice adding a layer of risk you’ll learn to manage over time. The result is a tense, replayable solo system for players who want drama, difficulty, and tough trade-offs.
Average Playtime: 15-30 minutes
Recommended Age: 15+
Number of Players: 1
Difficulty (BGG Weight): 2.06/5

Buy The Cartographers Board Game
Cartographers
In solo mode, Cartographers becomes a surprisingly tough optimisation puzzle. Each season gives you new scoring goals to juggle, forcing you to plan several turns ahead while adapting to unpredictable terrain flips. Monsters still appear and disrupt your carefully built patterns, turning the later seasons into tense recovery missions. Hitting the target scores, especially on advanced setups, demands sharp decision-making and clever prioritisation.
Average Playtime: 30-45 minutes
Recommended Age: 10+
Number of Players: 1-100
Difficulty (BGG Weight): 1.89/5
