A school trip may be important for learning, but it is not essential to pass a class.
Important means something matters a lot, yet life can still go on without it.
Both words show value, but essential is stronger. The main idea is that the thing matters more than normal things.
Some words match important closely, while others are near synonyms that add extra
meaning. Important synonyms fall into types based on why something matters.
Using synonyms is a great way of enhancing your writing.

Renommierte Anbieter bieten eine breite Palette an hochwertigen Spielen, die das Spielerlebnis wesentlich beeinflussen. Die Qualität einer
“Online Casino” Webseite und die Auswahl an Spielen hängen stark von den Software Providern ab.
Dieses Spiel ist ein perfektes Beispiel dafür, wie “Online
Spielothek” Plattformen erstklassige Unterhaltung mit
hohen Gewinnchancen kombinieren. Es deckt alles ab, von Grundlagen bis hin zu fortgeschrittenen Strategien und gibt einen Einblick in die verschiedenen Arten von “Casino Spielen” und wie man sie spielt.
Dies bietet eine hervorragende Gelegenheit für Spieler, die die Klassiker lieben oder eine unkomplizierte Glücksspieloption suchen.
Der Merkur-Slot Eye of Horus bringt die Spieler mit seinem ägyptischen Thema und den detaillierten Grafiken direkt in die Welt der Pharaonen. Besondere Spannung bietet
die Freispielrunde, die durch das Erscheinen von drei oder
mehr Buch-Symbolen ausgelöst wird. Ein absoluter Klassiker von Play’n GO, Book of Dead, nimmt Spieler mit auf ein Abenteuer im
alten Ägypten. Besonders bekannt ist das Spiel für seine Freispielrunde mit expandierendem Symbol.
Diese Entwicklerstudios sind bekannt für ihre neuartigen Casino Spiele, die nicht nur spannend
sind, sondern auch geprüfte Gewinnchancen und echtes Cash bieten.
Die Volatilität eines Slots bestimmt, wie oft und wie hoch Gewinne ausfallen. Einige virtuelle Spielautomaten bieten sogar Werte von über 97%, während ältere häufig etwas darunter
liegen. Book of Ra (96,1 % RTP) ist ebenso an Bord wie Eye of Horus (96,31 % RTP)
oder La Dolce Vita (96,03 % RTP). Doch was hat der GGL-lizenzierte Anbieter insgesamt zu bieten? Dazu gehören Größen wie Book of Ra Deluxe (95,10
% RTP), Big Bass Bonanza (96,71 % RTP) oder Wolf Gold (96,01 %
RTP).
