Alongside the classic guessing games, Onlinedle ships skill-based mini games played in quick rounds. Most take 1-2 minutes and target a different ability: visual memory, hearing, reflex, time perception, intuition, bluffing. Each has its own page; read the short intro below and click through for the detail.
A colour shows for 5 seconds, then disappears. You rebuild it with R, G and B sliders. Visual memory and colour calibration. See the Colordle page.
A pure tone plays between 220 and 1760 Hz. You can hear the target up to three times, then guess its frequency. No absolute pitch needed, knowing a few reference points is enough. See the Soundle page.
Wait while the panel is red, click the moment it turns green. Your average across three trials is the score. The schoolyard reflex test, played with the whole room. See the Reflexdle page.
You get a target duration, start a hidden timer and try to stop it on target. No digits on screen, only your internal count. See the Stopwatchdle page.
Same chess puzzle on every screen. Mate-in-1, 2 and 3 positions are mixed, and the first player to find the mate wins the round. The pool holds 4,000 Lichess puzzles. See the Chessdle page.
Split the shape on screen with a single straight line. Target is 50/50, the clock is 30 seconds, you get one attempt. Over 200 asymmetric shapes. See the Cutdle page.
The classic, played against everyone at the table at once. Score is wins minus losses, so you can finish a round below zero. See the Rock Paper Scissors page.
Pick a number from 1 to 10; the lowest number nobody else picked wins. Looks trivial, is pure game theory. See the Tekdle page.
