Reading Time: 5 minutes


With a population nearing 100 million, Vietnam is emerging as a key player in the Asian iGaming industry. Despite not being the largest market in the region, Vietnam has a growing online presence with tech-savvy young players. However, slow load times and download speeds pose both challenges and opportunities for operators. Special attention must be given to performance metrics such as load time, download speed, game size, and compression rate.

As Vietnam’s iGaming industry expands, meeting the expectations of Vietnamese players becomes more challenging. TESTA can help address the unique demands of Vietnam’s digital landscape. TESTA specializes in localized market research and benchmarking, providing insights for crafting successful iGaming experiences with optimal performance.

Based on these metrics, we identify top performers and underperformers in Vietnam and highlight how TESTA provides real-world data and benchmarks for the local iGaming industry.

Top 10 slot game providers in Vietnamese online casinos

TESTA surveyed the top 10 slot games in Vietnam using data from SlotCatalog. They compiled the ranking below based on collected first-hand real-world data.

Test method

TESTA utilizes a crowdtesting-based approach by partnering with local testers in Vietnam who assess the client’s games using their own desktops. Our standardized testing process involves accessing the online gambling website, logging in, searching for the specified games, and measuring and documenting the relevant metrics. The collected data, including video captures, is then submitted to TESTA for analysis.

Test parameters

In this test, we focus on the following metrics: game size, load time, and load speed. These metrics significantly impact player experience, as explained below.

  • Load time (seconds):
    • Measures how long it takes for the game to load in the foreground while the player waits.
    • The most important metric for player experience, noticeable by any user.
  • Load speed (MB/sec):
    • Represents how quickly the game reads assets from storage and loads them into active memory.
    • Helps identify bottlenecks that may slow down the app.
    • Fast load speeds with long load times, like Lucky Scarabs from Booming Games, may indicate areas for optimization or bugs.
  • Game size (MB):
    • The total size of the app.
    • Transferred (MB): The amount of data transferred from the server to the player, usually slightly larger due to network protocol communication traffic.
    • Compression rate (%): The percentage of data reduction achieved by compression.
    • Smaller file sizes mean less data transfer and usually faster performance, but optimization also affects actual load time.

Using these metrics, TESTA’s crowdtest benchmarking compared the real-world performance of the top live dealer game providers from Vietnam.
