Digital lottery platforms face design challenges organizing number selection interfaces that work across devices, accommodate different draw formats, and remain intuitive for users picking combinations. Grid layouts affect how quickly players make selections and how comfortable the experience feels during regular play. Lotto888 experiments with various organisational methods, balancing visual clarity against functional efficiency. Grid structure directly impacts user experience during the number selection process that forms the core interaction.
- Sequential row arrangement
Most platforms default to sequential numbering arranged in horizontal rows. Numbers 1 through 49 get displayed in rows of seven or ten, depending on the total number pool size and screen width optimisation. This familiar arrangement mirrors how lottery numbers appear on physical playslips, creating continuity between traditional and digital experiences. Row length decisions balance readability against scrolling requirements.
- Shorter rows need more vertical space, but keep all numbers in each row visible simultaneously.
- Longer rows reduce scrolling but force users to scan horizontally across more numbers to find their choices.
Platforms serving markets with larger number pools, like 1-90 games, face greater challenges fitting grids comfortably on screens.
- Color-coded grouping
Some platforms organise numbers into colored sections, helping players track selections across different numerical ranges. This visual differentiation speeds up number location and reduces selection errors from clicking wrong numbers in dense grids. Color grouping strategies include:
- Range-based coloring where 1-10 appears in one shade, 11-20 in another shade, continuing through the full number pool
- Alternating row colors create visual separation between horizontal number lines
- Selected number highlighting using contrasting colors, showing which numbers have already been picked
- Hot and cold number indicators using color intensity, showing frequently or rarely drawn numbers
Color schemes need sufficient contrast for users with color vision deficiencies. Platforms serving diverse user bases implement multiple color palette options in accessibility settings.
- Columnar vertical layouts
Vertical column organization suits mobile devices better than horizontal rows in some implementations. Numbers stack in columns of five or six, allowing users to scroll vertically through the full number range. This orientation matches how users naturally hold and interact with phones during one-handed use. Vertical layouts work particularly well for games requiring multiple number selections from the same pool. Players keep their thumbs positioned in comfortable reach while scrolling through available numbers. The downside involves more scrolling distance compared to grid arrangements, spreading numbers across both horizontal and vertical space.
- Quick pick integration
Platforms integrate random number generation directly into grid interfaces rather than separating this function into different screens. Quick pick buttons appear above, below, or beside selection grids, allowing instant automatic number selection without navigation away from the main picking interface. Quick pick placement variations include:
- Top-of-grid buttons generating full line selections instantly
- Individual line quick picks when purchasing multiple entries simultaneously
- Partial quick picks filling remaining numbers after manual selections
- Regeneration options replacing unsatisfactory random selections without clearing manual picks
Integration keeps random selection accessible throughout the picking process instead of forcing users to decide between manual or automatic selection before starting.
- Multiple board displays
Platforms selling entries for multiple draws simultaneously show several selection grids on one screen. This parallel display lets users pick different number combinations for each board without switching between separate entry forms. Grid arrangements stack vertically or display side by side, depending on the available screen width. Multi-board displays include board numbering, copy functions duplicating selections across boards, and individual board clearing without affecting other selections. These features streamline bulk entry purchases during rollover draws when users want multiple chances with varied number combinations.
