01Overview

The client already had a lottery app built around buying a ticket for a daily cash prize.

The job was to rethink that and give people more to do in the product.

I expanded the original concept into engagement mechanics, rewards, customization and a visual language that could hold all of it.

Three phone screens: a daily draw with a ticket button, a winning number result, and a top-up screen. — Fig. 01The daily draw, a winning result, and top-up amounts.

Scope

Product concepts beyond the original daily draw
Ticket selection, draws, results and the wallet
Challenges, streaks, virtual coins, collectible boxes and leaderboards
Profile customization: avatar frames, titles and achievements
A playful visual language shared across transactional and celebratory screens

Team: Designed at Appello for an Australian client that already had a basic daily-draw app.

Rethinking the core experience

The original flow was entering a daily draw. I looked at how that could sit inside a fuller app: ticket selection, upcoming draws, results and the account, with the newer reward features on the same navigation.

Fig. 01 is the home of that draw, the result when a ticket wins, and the top-up screen. Fig. 03 is choosing a number. The purchase sheet shows the ticket price and the current balance, and it offers an optional subscription. Sign-in asks for agreement to the terms.

Building a gamification system

A large part of the work was proposing mechanics that belong together: daily challenges, a streak, collectible boxes, virtual coins, a leaderboard and profile items.

A challenge pays coins. Coins open a box. A box can yield a frame or a title that then shows on the profile and in the rankings. Fig. 02 starts that loop. Fig. 04 is the reward, the rankings and the profile.

04Look

A different visual personality

This could not look like business software. The UI is saturated, the type is large, and a win or a new reward gets its own moment.

The same tab bar and the same yellow action run through the draw, the shop and the account, so the louder screens still navigate like one product.

05Reflection

The project was a basic daily cash-prize draw, redesigned as a wider consumer product: the ticket, the wallet, the rewards and a look of its own.
