Start with the information
JONGG tile sets change the artwork around the game. The numbers, characters and suit marks tell you which tile you have. Start there, then enjoy the flowers, birds and finishes.
What tells me which tile it is?
Look for the tile’s number and suit. Dots, bams and craks each run from one through nine; winds, dragons, flowers and jokers have their own marks. JONGG keeps game information consistent across tile sets, even when their materials, colors and decoration change.
If a symbol is unfamiliar, the tile guide explains the marks. The printable tile reference gives you another way to keep the names beside you.
What does Large Print change?
Large Print enlarges identifying numbers and letters where the tile uses them and emphasizes simpler suit symbols. Some marks, including Soap’s frame, stay the same. The tile keeps its identity and the game keeps its rules.
Compare the faces you find hardest to distinguish on the screen you use for play. A larger label may help you; a tile set preview alone cannot tell you how comfortable a whole hand will feel.
Try a few tiles before a full hand
Check whether you can distinguish a dot, a bam and a crak without relying only on color. Compare winds and dragons, then find a flower and a joker.
Look at the smaller tiles as well as the ones in your rack. Keep the room lighting and screen position you normally use.
If the symbols are new, try a short tile exercise before settling into a hand.
What did the readability review check?
On October 23, 2026, JONGG’s review covered 93 catalog entries in generated tile images. It inspected every face illustration and a back at 24 and 32 pixels wide, plus a smaller selection at 52 pixels with Large Print and color tags enabled. No missing face or cropped game-information mark was confirmed in those reviewed images.
Fine decoration became less distinct at the smallest size. The review checked fixed images, not play on every phone or tablet. It did not establish comfort for people with low vision or test glare, motion and touch controls. Those practical checks still matter, whatever a design’s contrast measurements say.
The 93 entries describe that dated review, not the number of tile sets available today.
