Experience & key features
Block Blast! is a free block puzzle game made by Hungry Studio for iOS and Android. Players drag coloured blocks onto an 8x8 grid, fill rows or columns to clear them and chain combos for points. On the Vietnam App Store it is listed under Valar Technology Corp (provider: Valar Technology Joint Stock Company) with Vietnamese online-game confirmation no. 49/GXN-PTTH&TTĐT, issued on 13 March 2024. The copyright line names Hungry Studio and the developer link goes to hungrystudio.com, so it appears to be the Vietnam release of the same game.
Beyond the classic mode, the App Store description lists an adventure mode and weekly challenges, and the international privacy policy mentions exchanging blocks with nearby players over Bluetooth and a voice-controlled game. In its own 8 January 2026 announcement, Hungry Studio reported 70 million daily and 300 million monthly active players as of December 2025.
The free app is ad-supported, and the Google Play listing states it has ads and in-app purchases. None of the pages opened publish an in-app price list. Block Blast!+ on Apple Arcade is a separate version that the publisher says has no ads or in-app purchases, but it requires an Apple Arcade subscription.
On privacy, the policy names advertising IDs and partner IDs such as Pangle and AppsFlyer, and the App Store label says data may be used for tracking. In October 2026, The Star reported a developer's claim that the game tunes difficulty to each player's ad value; Hungry Studio did not reply before publication. It fits players who want short sessions and accept ads; those who don't can consider the Apple Arcade version.

Privacy
The Vietnam App Store listing links to a Vietnamese-language privacy policy (updated 8 Nov 2025) under which the services are operated by ARETIS LIMITED. It lists the Google advertising ID, Pangle ID and AppsFlyer ID, and says device IDs such as GAID and IDFA may be shared with ad partners. The App Store privacy label says identifiers and usage data may be used to track users across other companies' apps and websites. The international policy (updated 2 Nov 2026) adds sensor data used for ad-fraud detection, says raw IP addresses are not retained, and says the voice game processes audio and camera input on the device.

Allegation that difficulty depends on a player's ad value
According to The Star, developer Ayomide Omolewa says decompiling the game showed difficulty varies by country, phone model and the ad revenue a player has generated. No authority has verified this, and Hungry Studio has not responded directly.
Read the full account
The Star (28 Oct 2026, syndicated from Inc./Tribune News Service) cites Omolewa's Instagram post, which has over 15 million views. He claims a rule in the code can deal a set of pieces that cannot fit on the board, ending the run with an offer to watch an ad to revive, and that it triggers only when the loaded ad is worth at least 3.5 times the previous one and the player is 1,000 points past their high score. This is one individual's analysis, not established by any regulator or audit. The Star says Hungry Studio did not reply before publication, and quotes Jason Wang, VP of Brand & Marketing, from a January 2026 release saying the game runs on an extensive A/B testing framework with more than 10,000 tests in 2025.
Vendor response
No direct response, per The Star. Hungry Studio's January 2026 release says only that the game runs on an A/B testing framework and does not describe how difficulty is tuned.

Why this score
The rules are just dragging blocks onto an 8x8 grid. The App Store lists 49 interface languages, and the Vietnam listing is described in Vietnamese.
Why this score
The App Store description lists an adventure mode and weekly challenges, and the international privacy policy mentions a voice game and Bluetooth block exchange. At its core it is still a simple block puzzle.
Why this score
Free to play, with an ad-free Apple Arcade version, but the free app has ads and in-app purchases. The pages opened list no Apple Arcade price or in-app price list.
Why this score
The Vietnam iOS build was last updated on 9 Nov 2026 (version 1.2.5) and requires iOS 15.0 or later. Ratings are high across three stores, but there are no independent performance measurements.
Why this score
Support is by email, plus a short FAQ on the website. No help centre or chat appeared on the pages opened.
Why this score
The policy is public and specific, but the App Store label says identifiers and usage data may be used for tracking, alongside several ad-partner IDs. Per the international policy, the voice game is processed on the device. There is an unverified allegation that ad data influences difficulty.
