Pro tip — heads up before you bookmark it

A note on Flash-based exercises

Many of ESL Tower's interactive exercises were built in Adobe Flash, which modern browsers no longer support. The printable PDFs and HTML5 quizzes still work, but interactive activities may not load without extra setup. Verify any exercise before assigning it to a class.

What is ESL Tower Grammar?

ESL Tower is a long-running free ESL directory. The guide.html page acts as a hub, linking out to grammar exercises, vocabulary exercises, pronunciation materials, classroom games, kids' resources, and printable worksheets across the publisher's network of sites (including ESL Games Plus and Kiz School).

The library is broad rather than deep: hundreds of self-grading quizzes, printable PDFs, hangman/snake-and-ladders style games, PowerPoint downloads, and a section of eBook zip archives. Navigation is plain — links to clickable categories — which makes it easy to skim but hard to search.

Two things to flag before you bookmark: (1) many of the older interactive exercises were built in Adobe Flash, which is no longer supported in modern browsers, so only the HTML5/PDF parts still work without extra plugins; (2) the publisher's broader network also includes content for kids and other subjects (math, Chinese), so stick to the grammar/vocab sections to avoid getting lost.

How teachers use it

ESL Tower works best for these specific things:

Printable handouts: the printable grammar and vocabulary PDFs work cleanly in any browser and reproduce well on paper.
Substitute teacher plans: leave a stack of self-grading quiz URLs by level; students can work independently for 30+ minutes.
Warm-ups and fillers: a quick grammar or vocabulary self-grading quiz while you take attendance.
PowerPoint downloads: the PPT and eBook zip archives are useful if you teach in a classroom with a projector and want ready-made slides.
Cross-referencing with ESL Games Plus: the same publisher runs ESL Games Plus with a more visual, game-focused interface — useful when you want variety.

Is it worth your time?

Yes — but treat it as a free resource library to mine, not a polished teaching platform. The printable PDFs and the few HTML5 exercises are genuinely useful. The Flash-era interactive exercises are mostly dead in modern browsers, which significantly reduces the value if you need interactive online practice.

Pair ESL Tower with a more modern free site (British Council Learn English for listening and grammar, AgendaWeb for printable variety) and one structured paid option (ESL Brains or Teach-This) for lesson plans that follow a current-events or CEFR-aligned progression.

Honest recommendation: keep the guide.html page bookmarked as a free printables library, but verify any specific exercise still loads before assigning it to a class. To be verified: whether the publisher plans a full HTML5 migration.

Frequently asked questions

What is ESL Tower Grammar?

A long-standing free ESL directory that aggregates grammar, vocabulary, pronunciation, and printable worksheets, plus classroom games. Part of a broader network of ESL Games Plus / Kiz School sites.

Is ESL Tower Grammar still working in 2025?

Yes, the directory page is live and links to a deep library of grammar and vocabulary exercises. Many interactive exercises still rely on Adobe Flash Player, which modern browsers no longer support by default — a notable limitation.

Is ESL Tower good for teachers?

Yes for quick, no-signup warm-ups and printable handouts. The self-grading quizzes work well for individual practice. The dated Flash-heavy interface is a real drawback.

What levels does ESL Tower cover?

Beginner through upper-intermediate/advanced grammar and vocabulary. There are also sections for kids and IELTS/TOEFL/SAT practice tests. No explicit CEFR labels on every exercise — to be verified for specific levels.

Can students use ESL Tower independently?

Yes for printable PDFs and the few HTML5 exercises. The Flash-based interactive exercises will not load in current Chrome, Edge, or Safari without extra setup.

What are the best alternatives?

AgendaWeb (similar printable-heavy style), British Council Learn English (more polished and modern), ESL Games Plus (same publisher network, more visual). For structured paid content: ESL Brains and Teach-This.
