New in 1.6: • Settings now shows your trial days left, plus one-tap "Unlock permanently" and "Restore purchases" — no need to wait to be gated first. • A clearer unlock screen: concrete benefits, "Pay once. No subscription. No ads.", and your own Battle IQ and geniuses-beaten recap once your trial ends. • The rating prompt no longer competes with the trial offer on the result screen. • A "More from the developer" link in Settings. • Refreshed keywords so IQ Battle is easier to find.

Battle first – new in 1.5: • Jump right in: no placement test, your first battle is free. • New result screen with Battle IQ as a game value, rematch and share right below. • Party mode for 3–6 players on one iPhone, with a podium. • Two players on one phone, now with your names. • Challenge links: share your score, friends play the same tasks. • New result cards, including genius wins. • A new way into the geniuses and many small improvements.

Friend battles your way: • Choose a Battle IQ range with sliders, on one iPhone or through Game Center. • Compare both players’ estimated Battle IQ directly in the result. A game value, not an IQ test. • Round points and time bonuses remain available in the details. • Continue existing battles unchanged.

More battles, more fun: • Challenge friends or play on one device directly from Battle. • More responsive answers, smoother timers and instant right/wrong feedback. • Short examples before each new task type – skippable, without using playing time. • More varied logic and figure puzzles, rising difficulty and gentler memory sequences. • Familiar geniuses, a playful new look and detailed round comparisons, including a team moment. • Delete or give up unfinished duels, with clear cues for whose turn it is. • New IQ lightning icon and subtle light and dark launch screens. • Clearer friend selection and both players’ match Battle-IQ game values on one device. New in this update: • A consistent paper look in light and dark, clear player colors and calmer animations. • Open battles first, a clearer profile and redesigned share cards. • Choose practice task types, untimed answers and self-paced examples. • Remember positions: five new spatial-memory tasks per practice. • Restored task review and a brief review of mistakes after speed practice. • Optional haptics. Existing battles and scores stay intact. - Dedicated Geniuses tab, directly tappable opponents, stronger contrast and a streamlined weekly league.

IQ Battle is easier to navigate, with clearer screens, a more readable timer and better instructions with examples. Reworked logic and figure puzzles, memory and speed tasks, vocabulary and knowledge questions. Answer reviews explain solutions more clearly. Battles on one iPhone make it clearer whose turn it is, with new handoff transitions. Geniuses such as Einstein are easier to recognize in the arena. Also improved: Game Center status recovery, small-screen layouts and accessibility.

New: Combine three or five practice rounds in Mixed Practice, with a language-free option. Individual practice rounds start when you are ready. After completing practice, you can review your answers. Share your daily result as a spoiler-free image card or your complete Battle-IQ profile with a radar and preview. Also improved: duel overview, Challenge Geniuses, Weekly League, Profile, avatar editing and usability on smaller screens.

This hotfix fixes a crash when switching between Battle, League and Profile. It also keeps the permanent one-time unlock and restoration reliable on fresh App Store accounts.
