Onlinedle ships skill-based mini games beyond the classic guessing format. Each runs in 1-2 minutes and exercises a different sense — visual memory, hearing, reflex, intuition, social reading.
A colour shows for 5 seconds, then disappears. Use R, G, B sliders to rebuild the colour from memory. Your reconstruction is compared with the real value; closeness determines the round score. Tests visual memory and colour calibration.
A tone plays at a frequency between 220 and 1760 Hz. You hear it up to three times, then guess the frequency. Musicians and audiophiles have an edge; absolute pitch isn't required, but knowing reference Hz values helps.
Three trials. The screen turns from red to green, and you click as fast as possible. Average reaction time across the three trials is your score. Schoolyard reflex test, multiplayer.
An invisible stopwatch runs. The target is to stop it at a specific second (e.g. 7.5s). The counter is hidden; you use your internal sense of time. Closest to the target wins.
Same chess puzzle on every screen. Find the mate or tactical motif in 1, 2 or 3 moves. First correct move wins the round. Pool has 1,000 puzzles, so repeats are extremely rare.
Multiplayer rock-paper-scissors. Each player faces multiple opponents simultaneously. Score is net wins minus losses, so you can finish at -2. Hidden in solo because one-player rock-paper-scissors is meaningless.
Each player picks a number 1-10. Whichever is the lowest unique pick (only one player chose it) wins the round. Classic game theory puzzle: the optimal pick depends on guessing what others will do. Multiplayer-only.
