What we read first
The first thing we read on a rummy app is the lobby, not the table. The lobby tells us how the platform thinks about its reader. A lobby that buries the format tabs in a hamburger menu is a lobby that has prioritised marketing over usability. A lobby that exposes the format tabs in the first screen is a lobby that has prioritised the reader.
The second thing we read is the table finding flow. A platform that lets the reader filter by table rupee value, ceiling, and number of players in a single screen has a usable table finding flow. A platform that requires three or four taps to filter is a platform that has not invested in the reader.
Thumb reach, the silent test
The thumb reach test is the silent test we run on every rummy app. The draw and discard buttons are the two most-used controls in the game. If the draw button is at the top of the screen and the discard button is at the bottom, the reader is moving their thumb across the screen on every turn, which is a real cost over a 30-minute session.
A platform that puts the draw and discard buttons in the bottom third of the screen, within thumb reach, is a platform that has thought about the small-screen experience. A platform that puts the controls at the top is a platform that has ported a desktop design to mobile without thinking about the reader.
Screen states that break
The screen states that break the experience are the ones the platform has not tested. The "hand in progress" state is usually well-tested. The "disconnected from the table" state, the "KYC pending" state, the "withdrawal in review" state, and the "time-out active" state are usually less well-tested.
A reader who has used a rummy app for 30 minutes has seen the happy path. A reader who has used a rummy app for a year has seen all the screen states. The year-long reader is the one who knows whether the platform has thought about the small-screen experience.
The table state, in detail
The table state is the most-used screen in a rummy app. A platform that has thought about the small-screen experience will show the player's 13 cards in two rows, with the open deck and the closed deck clearly visible, and the draw and discard buttons in thumb reach. A platform that has not thought about the experience will show the cards in a single row, the decks at the top, and the buttons at the top.
The single-row card layout is the most common usability failure we see. The reader's hand is 13 cards, and 13 cards in a single row on a 6-inch screen means the cards are too small to read. The two-row layout is the right move.
The lobby, in detail
The lobby is the second-most-used screen. A platform that has thought about the small-screen experience will expose the format tabs in the first screen, with the table rupee value and the ceiling as filter chips below the tabs. A platform that has not will require a tap to expose the formats, and another tap to expose the filters.
The lobby is also where the responsible-play controls should be reachable. A platform that has a "Responsible Play" button in the lobby has thought about the reader. A platform that buries the button in account settings has not.
The cashier, in detail
The cashier is the third-most-used screen. A platform that has thought about the small-screen experience will show the balance at the top, the deposit button below the balance, the withdrawal button below the deposit, and the responsible-play controls below the withdrawal. A platform that has not will require a tap to expose the deposit and withdrawal buttons, and another tap to find the responsible-play controls.
The cashier is also where the bonus balance is shown. A platform that shows the cash balance and the bonus balance separately, with the playthrough condition visible, is a platform that has thought about the reader. A platform that shows only the total balance, without the breakdown, is a platform that has not.
The KYC flow, in detail
The KYC flow is a one-time screen, but it is the screen that determines whether the reader can deposit and withdraw. A platform that has thought about the small-screen experience will let the reader upload the PAN, the address proof, and the bank proof from the camera roll or the camera, with a progress indicator. A platform that has not will require the reader to download a separate app, or to email the documents to support.
The KYC flow is also where the platform's responsiveness is tested. A platform that responds to a KYC submission within 24 hours is a platform that has invested in the reader. A platform that takes 72 hours is a platform that has not.
What we do not review
We do not review the visual design of the lobby or the table. The visual design is a matter of taste, and a review that ranks platforms on visual design is a marketing product, not a usability review. We review the controls, the screen states, and the responsive pacing.
We also do not publish a leaderboard. A leaderboard is a marketing product, and a usability review that ranks platforms is a leaderboard. We publish a usability shelf, with the same three measures for every platform we read.
The shelf, in three lines
The shelf is the same three measures for every platform: lobby and table finding, cashier and verification, and responsible-play controls. The shelf is not a ranking. The shelf is a reader's guide, and the reader is the one who decides which platform fits the format and the budget.
rop when the math is wrong). Two lines that exist outside any platform (the Government of India helpline, the iCare Centre). One play action, in the header, in the mobile drawer, in the mobile sticky bar. The reading desk is the part of the publication the reader can use to read the rummy field with a calm eye.
