Squares

By Alex Vasiliu, iOS Solution Architect

Squares is a tap and swipe puzzle game offering multiple distinct play modes to keep the experience fresh across extended sessions. Each mode introduces a different rule set around how coloured squares are matched or cleared, ranging from relaxed level-based progression to timed and competitive formats. Players personalise their experience with unlockable skins and visual themes, and GameCenter adds a social layer through direct challenges between friends online and shared score chasing with rivals. The challenge system tracks scores per mode independently, so friendly competition unfolds across whichever format each player enjoys most, giving the game strong replay value well beyond the initial level progression.
