Tempestr is a vertical casual strategy game that combines mahjong tiles and alchemy recipes as core mechanics. Players first need to check the target tile pattern at the top, then find the correct tiles from the floating and moving tiles on the field, and drag them in order into the twilight cauldron to complete the brew. Any wrong tile inserted consumes a chance, and when chances run out, the round ends. As the number of brews increases, the recipe steps become longer, more tile types appear, and the floating speed increases, testing observation and rhythm. Successful brews accumulate points and let you challenge higher records. The rules are clear and easy to pick up, but the sequence and timing offer strategic depth, making it suitable for short immersive sessions round after round.
