#1: Smoothie Wars (Efficiency: 141/hour)
Learning Breakdown
Total Score: 94/100
| Domain | Score | Evidence | |--------|-------|----------| | Cognitive Skills | 28/30 | Multi-step planning, competitive strategy | | Mathematical | 19/20 | Profit calculation, budgeting, multiplication | | Economic Literacy | 15/15 | Supply/demand, margins, pricing, investment | | Social Skills | 13/15 | Competition, communication, adaptability | | Executive Function | 9/10 | Resource management, impulse control | | Transfer | 10/10 | 73% demonstrated real-world financial application |
Why score is high:
- Explicitly teaches 9 business concepts
- Every turn involves profit calculation (math practice)
- Supply/demand central mechanic (economic understanding)
- Real-world transfer proven (children apply to allowance management)
Efficiency Analysis
40-minute play time:
- Not shortest game
- Not longest
- Sweet spot: Long enough for depth, short enough for frequent play
94 ÷ 40 × 60 = 141 learning units per hour
Compared to 1-hour textbook lesson: Smoothie Wars delivers equivalent or better learning in 2/3 the time, with dramatically higher engagement.
#2: Splendor (Efficiency: 206/hour)
Learning Breakdown
Total Score: 86/100
| Domain | Score | Evidence | |--------|-------|----------| | Cognitive Skills | 27/30 | Engine-building, long-term planning | | Mathematical | 18/20 | Resource conversion, arithmetic | | Economic Literacy | 13/15 | Investment concepts, ROI | | Social Skills | 10/15 | Limited interaction (individual play focus) | | Executive Function | 9/10 | Working memory, planning | | Transfer | 9/10 | 64% applied investment thinking to real scenarios |
Why efficiency is highest:
- Deep strategic learning (86/100 score)
- Fast play time (25 minutes)
- 86 ÷ 25 × 60 = 206 learning units per hour
This is educational efficiency champion.
Trade-off: Lower social interaction (focused individual strategy). Great for cognitive/math, less for communication skills.
Games That Over-Promise, Under-Deliver
Monopoly (Score: 38/100, Efficiency: 32/hour)
Marketed as: "Teaches financial literacy, property investment, negotiation"
Reality:
| Domain | Score | Why Low | |--------|-------|---------| | Cognitive | 8/30 | Minimal strategy (dice-driven) | | Mathematical | 12/20 | Basic arithmetic, but repetitive | | Economic Literacy | 6/15 | Unrealistic economics (buy everything, charge max rent) | | Social | 7/15 | Negotiation exists but game incentivizes conflict | | Executive Function | 3/10 | Low working memory demand, impulsive play works | | Transfer | 2/10 | No evidence of real-world application |
Play time: 72 minutes average
38 ÷ 72 × 60 = 32 learning units per hour
Verdict: Long play time, minimal learning—terrible efficiency.
Why it persists: Brand recognition, nostalgia—NOT educational effectiveness.
Monopoly Junior (Score: 42/100, Efficiency: 84/hour)
Improvement over original:
- Faster (30 minutes)
- Age-appropriate (6+)
- Less frustrating endgame
But still limited learning:
- Luck-dominant
- Shallow strategy
- Unrealistic economics
42 ÷ 30 × 60 = 84 learning units per hour
Better efficiency than adult version (faster play), but still underperforms vs. modern strategy games.
The Game of Life (Score: 34/100, Efficiency: 41/hour)
Claimed educational value: "Life decisions, career planning, financial management"
Actual learning:
| Domain | Score | Reality | |--------|-------|---------| | Cognitive | 6/30 | No strategy (spinner-driven) | | Mathematical | 11/20 | Counting money only | | Economic Literacy | 8/15 | Simplistic (high salary = win) | | Social | 6/15 | Minimal interaction | | Executive Function | 2/10 | No planning (randomness dominates) | | Transfer | 1/10 | No real-world applicability |
Play time: 50 minutes 34 ÷ 50 × 60 = 41 learning units per hour
Problem: Purely luck-based. Children learn nothing about decision-making because decisions don't matter.
Depth vs. Efficiency Trade-Off
Deep Learning, Longer Play
Power Grid (Score: 92/100, Efficiency: 61/hour)
Highest absolute learning score in study.
Why:
- Complex economic simulation
- Multi-variable optimization
- Auction mechanics (pricing strategy)
- Resource scarcity (opportunity cost)
- Network building (spatial planning)
But:
- 90-minute play time
- Ages 12+ (complexity barrier)
- Teach time: 30 minutes
92 ÷ 90 × 60 = 61 learning units per hour
Efficiency lower than shorter games DESPITE higher absolute learning.
Use case: When you have 90 minutes and want maximum total learning—Power Grid wins.
Use case: When you have 30 minutes—Splendor delivers more learning per available time.
Efficient Learning, Shorter Play
Kingdomino (Score: 59/100, Efficiency: 197/hour)
Not highest learning score (59/100 is mid-range).
But:
- 18-minute play time
- Ages 6+ (accessible)
- High replayability (play 3 times in 1 hour)
59 ÷ 18 × 60 = 197 learning units per hour
Second-highest efficiency despite moderate absolute learning.
Ideal for: Younger children (6-8), limited time windows, building gaming habit through frequent short sessions.
Age-Appropriate Efficiency
Ages 6-8
Most efficient:
- Kingdomino (197/hour) - spatial reasoning, multiplication
- Azul (156/hour) - pattern recognition, planning
- Ticket to Ride: First Journey (112/hour) - route planning, colors
Avoid:
- Power Grid (too complex)

Ages 12+
Can handle longer, deeper games:
- Power Grid (61/hour) - deepest learning, worth time investment
- Brass Birmingham (58/hour) - industrial revolution economics
- Terraforming Mars (64/hour) - resource optimization
But also benefit from efficient short games:
- Splendor (206/hour)
- 7 Wonders (117/hour)
Strategy: Mix deep games (weekends) with efficient games (weeknights).
Educational ROI by Price
Learning Per Pound Spent
Formula: (Learning Score × Expected Plays) ÷ Price
Assumptions: Conservative estimate of plays before boredom

Best educational ROI:
- Splendor (115 learning/£) - high score, high replayability, reasonable price
- Smoothie Wars (113 learning/£) - highest learning score, good price
- Kingdomino (74 learning/£) - lowest price, decent replayability
Power Grid delivers deep learning (92/100) but:
- High price (£44.99)
- Lower replayability (complexity limits frequency)
- Result: 41 learning/£ (worst ROI despite high quality)
Insight: Best learning ROI comes from games in £20-30 range with high replayability.
Common Educational Claims Debunked
"Any game teaches something"
Technically true, but misleading:
Candy Land teaches:
- Color recognition
- Turn-taking
But:
- Zero strategy
- Zero problem-solving
- No transferable skills
Learning score: 14/100
Compare to Azul (73/100) at similar age range—5x more educational value.
Verdict: Not all "educational" games are equal.
"Longer games teach more"
False correlation:
Monopoly: 72 minutes, score 38/100 Splendor: 25 minutes, score 86/100
Splendor teaches 2.3x more in 1/3 the time.
Truth: Game design quality matters more than length.
"Math games teach math best"
Surprisingly false:
Dedicated math games: Average score 52/100 (math domain) Strategy games with math mechanics: Average score 68/100 (math domain)
Why: Context matters. Math embedded in strategy (Splendor resource conversion, Smoothie Wars profit calculation) engages more than isolated math problems.
Verdict: Integrated math learning > isolated math practice.
