Every screen holds part of the information. Cooperate to arrive together and compete to contribute more. Circuito Cero is a deduction and adventure game for 2–6 nearby people, each with their own device. Combine private clues, turn-based decisions, and individual scores: if the team loses, nobody wins. SIX SCENARIOS, 62 MAPS • Frequencies: combine sums, differences, and odd/even clues. • Signal Patterns: discover a sequence and complete its pulses. • Lost Operators: reconstruct values and the +, −, and × symbols. • The Contradictory Sensor: identify the single false reading and solve the frequencies. • The Crossing: transport people, animals, and objects while respecting their restrictions. • Story: experience ten adventures where clues, items, and your decisions change what happens next. STORIES SHAPED BY YOUR TEAM Each traveler starts with two hearts, two private clues, and an item. Share up to two clues per decision, choose A, B, or C, and seek the best reward while keeping your team safe. Sometimes one person chooses the next path for everyone. Sacrifice an item to help another traveler or save it for a later opportunity. Decisions carry consequences: earning more now can make the next stage harder. During opportunities, lock in your intention, see the probability, and choose to prepare, attempt, or pass. Everyone must arrive alive. If anyone loses their final heart, the adventure ends for the whole team. If everyone arrives, the highest personal score wins; tied players share the victory. DEDUCTION, TURNS, AND LIMITED RESOURCES The 42 mathematical maps keep their three difficulty levels. Combine private readings from across the team and choose which to transmit: transmissions are limited. Correct answers earn points; mistakes reduce shared integrity. With two players, one initial hand can sometimes make deduction more direct. The Crossing keeps its ten maps, with three restriction variants per map. Story adds ten adventures with three causal variants and its own rules. FOR GATHERINGS AND TRIPS • Solo guided practice with Lía, a simulated teammate. • Illustrations bundled with the app. • Interface and clues in 21 languages; each device uses its own language. • No accounts, ads, or in-app purchases. • No countdown or internet connection required during games. PLAYING TOGETHER Apple devices require iOS/iPadOS 26 or later. Install the same version of Circuito Cero on each compatible device. Keep them nearby, enable Wi-Fi and Bluetooth, and grant the requested permissions. One person creates a room; the others find it and join from their screens. Install before you leave: the content is included, and progress is saved on your device. Guided practice does not require a second device. ## Is Circuito Cero safe?
