Guess the world's mountains, one clue at a time. Elevation, range, country, prominence, and first-ascent data — decoded peak by peak.
Peaktle is a free educational guessing game for mountaineers, geography lovers, hikers, and trivia fans. Each puzzle challenges you to identify a real mountain by reading progressively revealed clues built from public elevation and climbing-history data.
The dataset spans 500+ famous peaks across every continent — the Himalayan and Karakoram giants above 8,000m, the volcanic summits of the Andes and Cascades, the classic Alpine 4,000ers, African rift volcanoes, Seven Summits, national high points from Australia to Antarctica, and iconic climbing objectives worldwide.
All figures are approximate and intended for educational and entertainment purposes only.
Peaktle features over 500 famous mountains from every continent, including all 14 Eight-Thousanders, the Seven Summits, major Alpine peaks, national high points, iconic volcanoes, and classic climbing objectives.
The daily mountain is seeded from the UTC calendar date, so every player around the world sees the same target each day.
