IQ Boost Alternatives: Brain Teasers and Logic Puzzles

If you like IQ Boost's trick questions, Brain Test is the closest alternative, and the calmest: its listing promises no timers and no competition. Brain Out and Braindom play the same way with more absurd humor. All four show ads and sell hints. If what has worn thin is the "find out your IQ" framing, or the shop, a logic puzzle is the real change: Sudoku Royale is classic sudoku with no ads and nothing for sale.

Brightika's IQ Boost has been on the App Store since 2020 and has 52,157 US ratings. Its listing describes original, funny tasks where the obvious answer is often wrong, and lots of levels. It also leans hard on IQ: "Find out your IQ level", and a promise that you will see your IQ growing as you play. We do not make claims like that for any app on this page, ours included. What we can compare is what the apps contain and what they charge.

How each app pitches itself, and what it sells

Brain teaser apps differ less in their puzzles than in their tone and their shop. This table quotes each listing's pitch next to what it charges for.

About the IQ part

A puzzle game's level count is not an IQ test. IQ tests are standardized and scored against a population; a trick question that you crack after three tries, or after buying a tip, measures whether you spotted that trick. That does not make IQ Boost a bad game. It means the number it attaches to you is entertainment, the same way Brain Out's "What is your IQ level?" is.

In fairness, Sudoku Royale has a playful figure of its own: a Brain Age stat in the profile (it asks for your date of birth), next to a skills radar for speed, accuracy, vision, consistency and repertoire. Treat it the same way, as a way to follow your own games, not a measurement of your mind.

If you want more trick puzzles

Brain Test

Unico Studio's Brain Test is the best known game of this kind, and its listing reads like the opposite of IQ Boost's: no timers, no stress, nothing to prove. If you finish it, Brain Test 2 continues with story-based levels, and the same studio lists Brain Test 3 and 4. It sells lamps for hints and a weekly VIP Package with a free trial; one-time ad removal starts at $3.99. Our Brain Test alternatives page compares the hint economies in detail.

Brain Out

Eyewind's riddles are the most absurd of the group, with sound effects and joke answers. It shares IQ Boost's IQ framing, so switch for the humor, not for a change in tone. Its shop centers on keys; see the Brain Out alternatives.

Braindom

The widest variety: riddles, word tricks and short mysteries where you work out who is lying, run by a mascot called Brian. Its shop includes a Diamond Membership alongside one-time packs. The Braindom alternatives page covers it.

If the shop is the problem

IQ Boost's listing shows Remove Ads at 5 different prices ($4.99, $5.99, $2.99, $0.99, $1.99), some marked as sales, plus tip packs (Pile of Tips $1.99, Mountain of Tips $4.99, Bag of Tips $2.99) and a Startup Set. It has no subscription, which is a point in its favor next to Brain Test and Braindom. But every app in this genre earns from you getting stuck, and switching between them mostly changes the name of the hint currency.

Sudoku Royale (our app) sells nothing at all, so there is no tip to buy and no ad to remove. In Practice, its hint appears after about 90 seconds without progress and names the technique to use and the cell to look at, without giving away the digit.

If you want a puzzle you solve by method, not by a trick

An IQ Boost level is solved by one sideways insight. Once you have seen it, there is nothing left to work out, and the next level needs a different trick. Sudoku works the other way: the rules never change, and each technique you learn, from a hidden single to a naked pair, keeps paying off in every future puzzle. Nothing is hidden in the wording, so you never feel cheated by an answer.

Sudoku Royale has six levels from Easy to Extreme, a Journey of 88 levels that teaches one technique per chapter, and a Daily Challenge you can compare with friends. What it does not have next to IQ Boost: any humor or surprise, an Android version, undo, or a language other than English in the app.

When IQ Boost is still the better pick

• You want to laugh at the answer. Sudoku has no punch lines. Trick puzzle games do.
• You want variety from level to level. Every IQ Boost task is a new kind of problem; every sudoku is the same kind.
• You want no subscription in the shop. Among the trick puzzle apps here, IQ Boost's listing is the only one with no recurring item.
• You play on Android. Sudoku Royale is iPhone and iPad only.

Which to pick

Same kind of fun, less pressure: Brain Test. Same kind of fun, sillier: Brain Out or Braindom. A different kind of puzzle with no shop at all: try Sudoku Royale.
