Bet on the right answer and compact your way to victory! This game is all about strategy and argumentation in soil compaction. Answer, debate, wager, and win—if you have the courage to take the risk!
Content covered: soil compaction, compaction tests, compaction curves, the influence of dry density, degree of saturation, and practical applications in engineering projects.
Target audience: undergraduate Civil Engineering students, especially those in Soil Mechanics courses.
Number of players: 2 to 4 participants.
Average playtime: 30 to 45 minutes.
Game type: a quiz and betting game inspired by the Palpite Certo format.
Objective: Players answer questions about soil compaction and place bets on the answer they believe is correct. Each round allows for discussion and argumentation, encouraging players to defend their choices. The winner is the one who accumulates the most chips throughout the game, combining knowledge, strategy, and the courage to bet.
Format: physical print-and-play game, with simple instructions and colorful PDF cards.
How to use it: ideal for reviewing and deepening understanding of soil compaction concepts. The game promotes technical reasoning, peer-to-peer argumentation, and evidence-based decision-making. It can be used during class sessions or in teaching workshops, offering strong engagement potential.
What do you need?Only the PDF files available on this page, blank sheets, and a timer are needed. Simply print, cut, and fold the cards as instructed. No glossary, answer key, or any additional materials are required: the correct answers are already indicated on the cards themselves, allowing students to play independently with minimal teacher supervision.



By participating in the game, students develop key cognitive skills essential for mastering the topic. According to the Revised Bloom’s Taxonomy, the learning objectives include:


The game was supervised by Dr Mariana Chrusciak and Dr Bruna Lopes. All content and design were developed by Paula Perez, based on key soil compaction topics covered in the Soil Mechanics and Geotechnical Laboratory courses.
Before the final version, the game was tested with a focus group of students (Ethics Approval No. 85004824.2.0000.5302 – 2024 – UFRR), and the feedback was essential to improve the clarity of the clues, the balance of difficulty, and the overall game dynamics.
