Emoji Mixer: combine concepts while checking rendering support

Emoji Mixer is strongest as an exploration game, not a pure deduction test. I start with pairs that share a visual feature, an action or a familiar phrase, then vary one side while keeping the other fixed. That turns random tapping into a small experiment and makes the catalogue easier to map. With hundreds of combinations, a history of attempted pairs and a gentle category hint would matter more than a conventional difficulty curve. Some results will depend on cultural associations, so surprise is part of the design rather than proof of bad logic.
